Anand Jain April 30, 2015, 10:08 a.m. UTC
This test case tests if the device delete would work when
the source device has failed with EIO errors.

EIO errors are achieved usign the DM device.

Also this test needs the latest btrfs-progs and kernel patch
under title
  [PATCH] device delete by devid

When this patch is not found in the btrfs-progs, this test
will not run. However when the require patch is not found
in the kernel it will fail gracefully.
