Re: [PATCH] mdadm: fix reshape from RAID5 to RAID6 with backup file

["Tkaczyk, Mariusz" <mariusz.tkaczyk@xxxxxxxxxxxxxxx>]

Hello Nigel,

Blame told us, that yours patch introduce regression in following
scenario:

#mdadm -CR imsm0 -e imsm -n4 /dev/nvme[0125]n1
#mdadm -CR volume -l0 --chunk 64 --raid-devices=1 /dev/nvme0n1 --force
#mdadm -G /dev/md/imsm0 -n2

At the end of reshape, level doesn't back to RAID0.
Could you look into it?
Let me know, if you need support.

Thanks,
Mariusz
