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()
