From: Anand Jain <anand.j...@oracle.com> This test case tests if the device delete works with the failed (EIO) source device. EIO errors are achieved usign the DM device.
This test would need following btrfs-progs and btrfs kernel patch btrfs-progs: device delete to accept devid Btrfs: device delete by devid However when btrfs-progs patch is not found this test will not run, and when kernel patch is not found btrfs-progs will fail gracefully and thus the test script.
