Subject: imsm: set generation number when reading superblock
X-Git-Tag: mdadm-4.0~12

imsm: set generation number when reading superblock

IMSM doesn't set 'events' field with generation number, so sometimes mdadm
tries to re-assembly container using metadata which isn't most recent (e. g.
from spare disk).
