Hi all,

Use dm-error to simulate disk errors for written file extents and ensure
that the media scanner in xfs_scrub actually detects them.

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
