Sure, I'll add a test case to verify the single-data-RAID56 behavior for 
btrfs.

Not sure what specific workload you may want to verify, but my planned 
workload is:

- Create single-data-RAID56 btrfs
- Fsstress it
- Unmount

- Mount with one device missing, readonly
- Do a readonly scrub, should be no error
- Retry with the remaining device(s)

If you have something else to add, I'm pretty happy to add.

Thanks,
Qu
