        - Fix two byte count size wraps in xfs_copy.
        - Minor man page fixes from Eric Raymond.

xfsprogs-2.6.18 (23 June 2004)
        - Fix libhandle from possibly returning an invalid
          handle length on systems where size_t is 64 bits.
        - Minor autoconf fixups to get rpm test working on
          all platforms again.
        - Minor man page updates fixing minus/hyphen usage.

xfsprogs-2.6.17 (23 June 2004)
        - Fix use of isset macro, getting realtime devices to
          function correctly in xfs_db and xfs_repair.
        - Fix initialisation of realtime devices in libxfs.

xfsprogs-2.6.16 (17 June 2004)
        - Add sendfile command into xfs_io(8) to exercise that
          functionality.
        - Remove maxtrres program that was used in the build
          to generate a header for mkfs' consumption.
        - This allows cross-compiles to be greatly simplified.
        - Portability tweaks for building on other platforms.
        - Fix obscure bug in log size lower boundary checks for
          auto-sized logs when stripe alignment is in effect;
          the enforced lower bound could have been set too low.

xfsprogs-2.6.15 (09 June 2004)
        - Make xfs_check test for a dirty log before proceeding to
          check the filesystem.
        - Fix couple of minor bugs in xfs_io (readonly handling on
          writes, off-by-one error in open file error reporting).

xfsprogs-2.6.14 (13 May 2004)
        - Allow logprint to copy a log to a file (-C) and to dump
          a log from beginning to end showing ondisk log record (-d).
        - Fix logprint handling of -f option - shouldn't be doing
          the UUID check in that case, since we don't have the SB.
        - Remove MD device superblock "clean" check, following Neil
          Brown's advice.
        - Small Debian packaging tweak to say xfsprogs has an fsck.

xfsprogs-2.6.13 (03 May 2004)
        - Zero out more at beginning and end of device at mkfs time
          (get all old MD superblocks at the end, for mount by label).

xfsprogs-2.6.12 (30 April 2004)
        - Extract stripe unit/width from device mapper devices
          (added libdisk infrastructure, used by mkfs.xfs).
        - Fix rounding in xfs_io(8) bytes read/written output.
        - Sync up user/kernel source in libxfs and headers.
        - Fix compiler warnings on 64 bit platforms.
        - Update i18n message catalog.

xfsprogs-2.6.11 (15 April 2004)
        - Fix file descriptor leak in path_to_fshandle. A file
          was being opened but never closed, regardless of
          whether that descriptor was being cached. Now close
          the file on error or if it is not being cached.
        - Fix xfs_repair handling of a corrupt v2 directory with
          multiple entries having the same name.

xfsprogs-2.6.10 (05 April 2004)
        - Fix botch in recent addition of new superblock field
          (features2) which could result in filesystems with v2
          logs being created with invalid superblock fields.
          Thanks to Chris Pascoe for this fix.
        - Fix error when forcing a too-large v2 log stripe size
          back to 32K.  Thanks to Chris Pascoe for this fix too.
        - Fix xfs_copy -d option so that it really does create a
          duplicate filesystem (the log is duplicated too now in
          that case, whereas previously a fresh log was created).

xfsprogs-2.6.9 (26 March 2004)
        - Update HFILES in xfsprogs/io/Makefile to package io/io.h

xfsprogs-2.6.8 (25 March 2004)
        - Fix xfs_db when dumping v2 dirs larger than the fsb size.
        - Several xfs_io additions - support for memory mapped areas,
          multiple open files, expert mode (freeze, shutdown, error
          injection, etc), fadvise (Linux-specific), allow user to
          specify a create mode to open(2).
        - Fix xfs_bmap verbose mode stripe alignment information.
        - Fix typo on xfs(5) man page.

xfsprogs-2.6.7 (19 March 2004)
        - Fix up UUID library checks again, previous fix didn't work
          for older versions of autconf.
        - Allow for future extensions to the XFS ondisk structure by
          reserving an extra 32 bits in the superblock for feature
          bits (update xfs_db to dump them).
        - Fix xfs_repair handling of version 2 directories with a
          hole at the start.
        - Fix an endian bug in xfs_copy, when operating on allocation
          groups with multi-level freespace btrees.
        - Ensure xfs_repair "dangerous" mode does not attempt to set
          the device blocksize, this generates an error when target
          filesystem is mounted readonly.

xfsprogs-2.6.6 (03 March 2004)
        - mkfs now opens the devices it's operating on with the
          O_EXCL flag set, which is used by the Linux 2.6 block
          layer to ensure concurrent access does not happen.
        - Allow xfs_io to operate on files from other filesystems,
          with the XFS-specific commands unavailable in this mode.
        - Fix configure scripts to also search for a UUID library
          in /usr/lib64 which is its home on AMD64/x86_64.

xfsprogs-2.6.5 (20 February 2004)
        - Fix up mkfs to ensure that the log size is a multiple of
          the v2 log stripe size even if the log happens to be aligned
          on a log stripe boundary (always check it).

xfsprogs-2.6.4 (17 February 2004)
        - Fix a few more libxfs/repair leaks.
        - Fix up some libhandle routines, add the open_by_fshandle
          routine required by recent versions of xfsdump.

xfsprogs-2.6.3 (19 January 2004)
        - Merge Steve Langasek's work on the Debian installer
          support for xfsprogs.
        - Add knowledge to xfs_db about the security namespace in
          its extended attributes commands.
        - Sync up user/kernel source in libxfs and headers.
        - Fix a couple of compilation warnings.
        - Workaround for some versions of autoconf mishandling the
          AC_CHECK_SIZEOF macro.
        - Fix a memory leak in libxfs, most noticable in xfs_repair.

xfsprogs-2.6.2 (17 December 2003)
        - Fix dev_t sizing issues in user tools - glibc uses a 64
          bit number and XFS has a 32 device bit number, confusion
          reigns.  Not much manipulates device numbers in the XFS
          user tools though, hence hasn't really been seen before.
          Thanks to Christoph for the patch.

xfsprogs-2.6.1 (27 November 2003)
        - Human-friendly xfs_io read/write bsize specifications.
        - Dump throughput and IOPs values after xfs_io reads/writes.
        - Sync up user/kernel source in libxfs, libxlog and headers.

xfsprogs-2.6.0 (28 October 2003)
        - Change to mkfs strategy for allocation group count and size
          default.  Scales significantly better for large filesystems.

xfsprogs-2.5.11 (10 October 2003)
        - Incorporate Jan Derfinaks change to the Linux block ioctls
          used in libxfs, allowing this code to compile cleanly with
          include files from Linux 2.6.0-test5 onward.

xfsprogs-2.5.10 (30 September 2003)
        - Fix up xfs_logprint to handle version 2 logs for its
          operation output (previously core dumped on it).

xfsprogs-2.5.9 (19 September 2003)
        - Sync up user/kernel source in libxfs, libxlog and headers.
        - Add new inode flags into xfs_db too.

xfsprogs-2.5.8 (12 September 2003)
        - Add missing options to xfs_db frag command one-line summary.
        - Add xfs_io commands for setting and clearing new inode flags
          for immutable/append-only/sync/no-atime/no-dump.
        - Dump some other statfs fields in the xfs_io statfs commands.
        - Remove "test" mode from xfs_repair, only useful in xfs_check.
        - Fix problem in xfs_logprint where it was trying to continue
          in the presence of a corrupt log when it shouldn't have.
        - Fix an incorrect assertion in xfs_logprint in regards to the
          validity of the log start block.
        - Fix xfs_growfs (and hence xfs_info) to allow it to be given
          either a mount point or a device in the mount table - it'll
          figure it out and should do the right thing either way now.

xfsprogs-2.5.7 (29 August 2003)
        - Sync up user/kernel source in libxfs and headers.
        - Make xfs_copy a tad more portable, although work remains.
        - Add a "test" mode to xfs_repair and xfs_check which allows
          for sparse (and hence extremely large) filesystem testing.

xfsprogs-2.5.6 (19 August 2003)
        - Fix a mkfs problem where it could exit inappropriately when
          a large data volume stripe unit was either specified on the
          command line or via querying the underlying volume manager.

xfsprogs-2.5.5 (07 August 2003)
        - Update xfs_io command to allow reading from non-XFS files.
        - Sync up user/kernel source in libxfs, libxlog and headers.
        - Update xfs_db and xfs_logprint commands to print new inode
          flush iteration field.

xfsprogs-2.5.4 (23 July 2003)
        - Update xfs_io bmap command to report unwritten extent flag
          if it is set on an extent (in verbose mode only).
        - Introducing xfs_copy.
        - Fix shell quoting problem in xfs_bmap script.

xfsprogs-2.5.3 (07 July 2003)
        - Update xfs_io commands which take user input in terms of
          byte counts to now also allow unit prefixes like mkfs.xfs.
        - Tweak build to avoid unnecessary rebuilds of international
          language files (if present), suggested by Steve Langasek.
        - Fix usage message in mkfs.xfs, it was out of date.
        - Fix some filesystem type detection code, in particular the
          bfs probe code was broken for 64 bit machines (found by QA
          test 032) and the hfs code was broken too (originally found
          by Ethan Benson).  We now also detect hfs+ filesystems.

xfsprogs-2.5.2 (25 June 2003)
        - Fix xvm stripe detection in libdisk - pass correctly
          sized structures to xvm ioctls.
        - Add pthread library checks into configure and build scripts
          for work-in-progress on xfs_repair and xfs_copy.
        - Fix missing initialisation of stripe unit/width alignment
          information during libxfs_mount.
        - Fix botched repair typecast for multi-terabyte filesystems.

xfsprogs-2.5.1 (23 June 2003)
        - Fix libdisk device driver (volume managers) detection code
          used by mkfs, so that drivers with multiple majors are not
          incorrectly processed.

xfsprogs-2.5.0 (18 June 2003)
        - Fix libdisk (and hence mkfs) code which warns on MD devices
          with the clean flag not set, apparently this is not so wise.
        - Fix libxfs_device_zero to work with smaller-than-requested
          write return values.
        - Fix error in xfs_io pwrite code with large request sizes.
        - Fix rounding-down-input problems in several xfs_io commands.
        - Changed mkfs.xfs default log size scaling algorithm slightly,
          to create larger logs at smaller filesystem sizes by default
          (thanks to Andi Kleen for the patch).
        - Enable support for sector sizes larger than 512 bytes.

xfsprogs-2.4.12 (02 June 2003)
        - Fix xfs_logprint handling of any version 2 log device.
        - Remove calls to exit in libhandle, propogate errors to
          caller, and bumped libhandle version from 1.0.1 to 1.0.2.

xfsprogs-2.4.11 (30 May 2003)
        - Extract device sector size at mkfs time and issue warnings
          if the requested filesystem sector size is too small.
        - Sync up user/kernel source in libxfs, libxlog and headers.
        - Skip realtime initialisation in libxfs mount path if the
          caller is xfs_db, otherwise we get nonsense warnings.
        - Update xfs_io with a couple of additional commands.
        - Fix xfs_logprint handling of corrupt v2 log devices.

xfsprogs-2.4.10 (12 May 2003)
        - Fix a bug in mkfs - creating version 2 logs, an incorrect
          stripe unit value was being passed to libxfs_clear_log.
          All recent versions of xfs_repair will fix this, however,
          because xfs_repair uses the correct stripe unit value.
        - Fix a bug in xfs_logprint, when dumping a corrupt log.
        - FreeBSD updates from Alexander Kabaev.
        - Large sector size updates for mkfs (disabled at the moment).
        - Large sector size fixes for xfs_repair.
        - Sync up with aeb's mount source for filesystem detection.

xfsprogs-2.4.9 (03 May 2003)
        - Allow xfs_repair to run on read-only filesystems.

xfsprogs-2.4.8 (26 April 2003)
        - Rework configure.in to make use of shared macros.
        - Fix up #include lines to allow compilation of sources
          with installed headers rather than local headers.
        - Fix botches in xfs_bmap shell script which prevented any
          arguments being passed on to xfs_io (from Jan Derfinak).

xfsprogs-2.4.7 (22 April 2003)
        - Clarify XFS system call interfaces, fix up documentation.

xfsprogs-2.4.6 (11 April 2003)
        - Fix a bug in detection of "clean" and "error" states with
          MD devices.
        - Fix configure tests that used AC_PATH_PROG incorrectly.
        - Add support for libedit, if libreadline is unavailable.
        - Fix the libxfs build on big endian platforms.
        - Sync up user/kernel source in libxfs and headers.

xfsprogs-2.4.5 (03 April 2003)
        - Sync up xfs_inode.c in libxfs.
        - Implement get_unaligned/put_unaligned in libxfs.

xfsprogs-2.4.4 (30 March 2003)
        - Correct display of imaxpct in mkfs.xfs output.
        - Portability changes; including some code to support use
          of several tools on Mac OS X (for Russell), ditto for
          FreeBSD (from Russell); also did a simplistic backport
          to IRIX (for me), so that I can run purify on some of
          the tools.
        - See doc/INSTALL for more details on this.
        - Sync up user/kernel source in libxfs and headers.
        - Fix up some warnings when compiling libxfs on big endian
          platforms.
        - Fix a configure.in botch which resulted in libreadline
          always being used even when it was not asked for.
        - Fixed the configure.in script so that if gettext disabled,
          we don't check for the gettext tools (and no longer fails
          if they were not found).
        - Added the ability to specify a different user and/or group
          to install as (previously, and still by default, root/root
          were always used here).

xfsprogs-2.4.3 (27 March 2003)
        - Cleanups to the build process, in particular the automatic
          rpm package generation Makefile and spec file template.
        - Makepkgs script can now propagate failures back from make.
        - Minor configure.in update to deal with readline libraries
          which have not been linked correctly.

xfsprogs-2.4.2 (25 March 2003)
        - Added the xfs_io(8) command, an xfs_db(8) alike command
          for testing and debugging the XFS file IO path.
        - Added an optional dependency on the GNU readline library
          which is "off" by default and enabled with the configure
          option --enable-readline=yes; it affects the interactive
          tools only (xfs_db and now xfs_io).
        - Implemented xfs_bmap(8) as a shell script wrapper.
        - Documented the mkfs.xfs -f, -llogdev and -rrtdev options.
        - Corrected size check for realtime summary inode (not the
          same as the realtime bitmap inode) in xfs_repair.

xfsprogs-2.4.1 (18 March 2003)
        - Fix error reporting when zeroing parts of the realtime
          device in phase6 of xfs_repair.
        - Add a mkfs.xfs check for Mac partitions before writing
          to the device.
        - Thanks to Ethan Benson <erbenson@alaska.net> for this.
        - Minor fix to the xfs_bmap(8) man page.
        - Sync up user/kernel source in libxfs and headers.

xfsprogs-2.4.0 (06 March 2003)
        - Enable unwritten extents by default in mkfs.xfs.
        - Add a command to xfs_db to enable unwritten extents.
        - Add an option to xfs_admin to use the above command.
        - Add command to xfs_db to print out the currently enabled
          feature bits and version number.
        - Make xfs_db slightly more robust in the presense of bad
          ondisk data.
        - Rationalise some xfs_db superblock-related code and the
          uuid command now checks for a dirty log before zeroing.
        - Add stripe alignment information to xfs_bmap.
        - Sync up user/kernel source in libxfs and headers.
        - Update man pages, fix a typo in the xfs_admin man page
          relating to the UUID options.

xfsprogs-2.3.11 (18 February 2003)
        - Missed a build dependency for the Debian build process.

xfsprogs-2.3.10 (17 February 2003)
        - Fix a divide-by-zero error in mkfs with certain stripe unit
          and/or width options specified.
        - Sync up user/kernel source in libxfs and headers.

xfsprogs-2.3.9 (31 December 2002)
        - Additional xfs_repair check in v2 directory handling for blks
          with no data entries (merged from IRIX), includes several
          handy comments sprinkled throughout this v2 dir code.
        - Fix an endian bug in the same area of code (v2 dirs, phase 6,
          longform_dir2_rebuild_setup)
        - xfs_repair has additional checks for bad sector values now.
        - xfs_repair I18N changes.
        - Fix detection of readonly mounts, slightly botched in 2.3.8.
        - Fix references to removed ioctl commands on xfs(5) man page.

xfsprogs-2.3.8 (18 December 2002)
        - Initial support for I18N (still more to do here).
        - Initial changes for filesystems with greater than 512 byte
          sector sizes (still plenty more to do here too).
        - Tidy up libxfs functions which take a "flags" argument.
        - Sync up user/kernel source in lib{xfs,xlog} and headers.
        - Fixed incorrect use of XFS_FSB_TO_DADDR macro in xfs_db's
          faddr.c::fa_dirblock routine - now use XFS_FSB_TO_BB here,
          as set_cur() takes basic blocks as its third parameter.
        - Fixed obscure issue in mkfs where only the first AG would
          get its AGFL freelist "fixed" - not clear this caused any
          issues in practice (on Linux it's always been this way, we
          now match up with IRIX though).
        - Made xfs_growfs filesystem geometry output match up with
          that displayed by mkfs.xfs (xfs_growfs was missing a comma
          before the log version field).
        - Fixed an issue in xfs_repair where data past the end of the
          valid superblock fields was sometimes not cleared, when it
          really should have been (due to a libxfs problem).
        - Shell scripts (xfs_info, xfs_check, etc) now also report
          the xfsprogs version number via -V, like other commands.

xfsprogs-2.3.7 (14 November 2002)
        - Fix an endian bug in xfs_db freesp command when descending
          into multi-level agf cnt/bno btrees.

xfsprogs-2.3.6 (31 October 2002)
        - Sync up user/kernel source in lib{xfs,xlog} and headers.
        - Fix several warnings from newer (3.2) versions of gcc.
        - Minor header file shuffling.

xfsprogs-2.3.5 (10 October 2002)
        - Sync up user/kernel source in lib{xfs,xlog} and headers.
        - Fix mkfs (libxfs) bug when using BLKFLSBUF ioctl - we passed
          in the device number instead of a file descriptor (and EBADF
          was the end result, which we ignored).
        - Thanks to Anton Blanchard <anton@samba.org> for fixing this.

xfsprogs-2.3.4 (04 October 2002)
        - Fix size calculation bug in xfs_repair's memory allocation,
          reduces memory usage by a factor of 4.

xfsprogs-2.3.3 (16 September 2002)
        - Fix mkfs bug when optimizing AG size on striped devices,
          ASSERT(agcount != 0) tripped on single-ag filesystems.

xfsprogs-2.3.2 (10 September 2002)
        - Use pread/pwrite instead of lseek + read/write.

xfsprogs-2.3.1 (03 September 2002)

        - Don't auto-grow the log to be larger than an AG
        - Change the error philosophy for -d su=,sw= away from forcing
          the XFS stripe size to match the volume manager stripe size
          and instead accept, with a warning, the stripe unit & width
          supplied on the commandline.
