IMSM regresion

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

Hello Jes,

We discovered IMSM regression after last push 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.

This is an information. We are working on fix. Please don't mark release 
candidate yet.
