  Add corrupt_bio_byte feature to simulate corruption by overwriting a byte at a
  specified position with a specified value during intervals when the device is
  "down".

  This target is the same as the linear target except that it returns I/O
  errors periodically. It's been found useful in simulating failing
  devices for testing purposes.

  I needed a dm target to do some failure testing on btrfs's raid code, and
  Mike pointed me at this.
