| |
4.3-stable review patch. If anyone has any objections, please let me know.
------------------
From: xuejiufei <xuejiufei@huawei.com>
commit c95a51807b730e4681e2ecbdfd669ca52601959e upstream.
When recovery master down, dlm_do_local_recovery_cleanup() only remove the $RECOVERY lock owned by dead node, but do not clear the refmap bit. Which will make umount thread falling in dead loop migrating $RECOVERY to the dead node.
