Subject: [PATCH -next v2 5/6] md: wake up 'resync_wait' at last in md_reap_sync_thread()
From: Yu Kuai <yukuai3@...wei.com>
md_reap_sync_thread() is just replaced with wait_event(resync_wait, ...)
from action_store(), just make sure action_store() will still wait for
everything to be done in md_reap_sync_thread().
