To: david, darrick.wong; +Cc: linux-ext4, fstests, linux-btrfs, xfs
Introduce tests for XFS and ext4 which format a filesystem, populate
it, then uses blocktrash and e2fuzz to corrupt the metadata. The FS
is remounted, modified, and unmounted. Following that, xfs_repair or
e2fsck are run until it no longer finds errors to correct, after which
the FS is mounted yet again and exercised to see if there are any
errors remaining.

Move the cp --reflink tests from btrfs/ to generic/ since xfs now
supports that ioctl.
