Subject: Add xfs_io into xfsprogs, an xfs_db-alike program for the XFS IO path
X-Git-Tag: XFS-1_3_0pre1~35
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=043c3c62c97a00501dc2262925c11760cfee604d;p=thirdparty%2Fxfsprogs-dev.git

Add xfs_io into xfsprogs, an xfs_db-alike program for the XFS IO path
which knows about direct IO, space preallocation, realtime files, etc,
which the usual tools like dd don't unfortunately.
