Subject[PATCH -next 0/6] md: fix that MD_RECOVERY_RUNNING can be cleared while sync_thread is still running
Date
From: Yu Kuai <yukuai3@huawei.com>

Patch 1 revert the commit because it will cause MD_RECOVERY_RUNNING to be
cleared while sync_thread is still running. The deadlock this patch tries
to fix will be fixed by patch 2-5.

Patch 6 enhance checking to prevent MD_RECOVERY_RUNNING to be cleared
while sync_thread is still running.

Yu Kuai (6):
Revert "md: unlock mddev before reap sync_thread in action_store"
md: refactor action_store() for 'idle' and 'frozen'
md: add a mutex to synchronize idle and frozen in action_store()
md: refactor idle/frozen_sync_thread()
md: wake up 'resync_wait' at last in md_reap_sync_thread()
md: enhance checking in md_check_recovery()
