Subject: dm raid1: fix to commit pending clear region requests
From: Jonathan Brassow <jbrassow@xxxxxxxxxx>
With the code as it is, it is possible for oustanding clear region requests
never to get flushed when a mirror is deactivated or suspended. This means
there will always be some resync work required when a mirror is activated,
even though it may very well be in-sync.
Always requesting the flush doesn't hurt us. This is because the log tracks
whether any changes occurred and, if not, no flush is performed.
