Hi Folks,

This is the first real "works ok" CRC patchset for xfsprogs. It
provides full support for mkfs.xfs and xfs_repair, and partial
read-only support for xfs_db.

For mkfs.xfs, it does everything properly, and filesystems that are
freshly made also run cleanly through xfs_repair and mount and run
just fine.

This seemed to be worthy of early note:

xfs/031 30s ...[ 587.843478] XFS (sdb6): Version 5 superblock detected. This kernel has EXPERIMENTAL support enabled!
[  587.843478] Use of these features in this kernel is at your own risk!
*** Error in `/sbin/mkfs.xfs': malloc(): smallbin double linked list corrupted: 0x0907f7d0 ***

The test doesn't seem to finish, but Ctrl-c ends the test cleanly. No dmesg stuff is added, and strace doesn't show anything between the mount message and the error message. I'll need to re-enable tracers to provide a trace...and as traces can be huge, I'll wait on your advice.

[BTW, the "30s" reference time is from the non-CRC run of your patched xfsprogs. The non-CRC run looked good.]
