Subject: [PATCH 22/22] Medium: Raid1: Ignore transient devices after stopping
a device (bsc#1077416)
There may be a transient invalid device after we stop the MD due to
other programs processing uevent, the original device is stopped though
(`mdadm --stop` only returns when MD is stopped).
The idea suggested by Neil Brown <nfbrown@suse.com>.
