This test will: 1. Create a 5-disk RAID5 2. Corrupt one of the device 3. Mount the FS as degraded 4. run btrfs scrub In bug 1812845 it just skipped step 2 and 3, and Andrea's patch states that this is caused by finish_parity_scrub(), so I think they're the same. If that's the case we should disable this test for now.
