Subject: [PATCH 29/29] 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>.
