This patch series adds crcs for btree blocks. The first three patches
contain some preparatory work, and the final one implements the actual
extended btree blocks with crcs and a uuid / blkno pair to identify out of
place writes. Note that this is only the start of CRC enabling XFS and it
will be followed by more patches later.
To actually create a CRC enabled filesystem you will need a patched xfsprogsa
. A quilt series with all required patches against current xfs-cmds CVS HEAD
is here:
http://verein.lst.de/~hch/xfs/xfs-cmds-crcs.tgz
Please note that the xfs-cmds patch series is not quite in a submittable
shape yet, and will always create CRC enabled filesystems with these
patches applied.
