Remove default sizeof sizes in configure script when cross-compiling
Since version 2.50 autoconf fully supports checking sizes of types
(with AC_CHECK_SIZEOF) when cross-compiling. Therefore there is no
need to preset the respective cache variables anymore. The following
patch removes the special case. There is no need to adjust AC_PREREQ
as it's set to 2.50 already.
Tested successfully cross-building for the mips64el-linux-gnu host on
an i386-linux-gnu build system, removing the following warning
(because of a mismatch for the "long" type):
Sizeof(__U64__TYPEDEF) is 4 should be 8

e2fsck: Fix potential data corruptor bug in journal recovery
While synchronizing e2fsck's recovery.c with the latest 2.6 kernel
sources, I discovered a serious bug that apparently had been fixed in
the kernel sometime between Deceber 2003 and April 2005, but which had
not been carried over to e2fsprogs. Specifically, when blocks whose
first 4 bytes are JFS_MAGIC_NUMBER (0xc03b3998) are written into the
journal, the first 4 bytes zero'ed out. A one character typo meant
that when the blocks were replayed by e2fsck, the JFS_MAGIC_NUMBER
would not be restored.
Oops.
Fortunately, it is *highly* unlikely that ext4 metadata blocks will
contain that magic number in the first four bytes, and data=journalled
is a relatively rarely used.
This commit fixes this bug, as well as updating e2fsck's recovery.c to
be in sync with 2.6.25.
blkid: Keep cached filesystem information on EACCES and ENOENT errors
When a nonprivileged user uses the blkid command, we want to keep the
cached filesystem information, and opening a device file could result
in an EACCESS or ENOENT (if an intervening directory is mode 700). We
were previously testing for EPERM, which was really the wrong error
code to be testing against.
In current git there is a double free on ctx->filesystem_name in the
end of main() and in e2fsck_free_context, causing e2fsck to abort at
the end of pass5.
The m_no_opt test has been silently failing since the addition of
mke2fs.conf, since it was trying to use resize_inode on a non-sparse
filesystem. Fix it so it works correctly.

Fix ext2fs_swap_inode_full() for in-inode xattrs on big-endian machines

Looks like the problem is that ext2fs_swap_inode_full()
