4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shaohua Li <shli@xxxxxx>
commit afc1f55ca44e257f69da8f43e0714a76686ae8d1 upstream.
->safemode should be triggered by mdadm for external metadaa array, otherwise
array's state confuses mdadm.
Fixes: 33182d15c6bf(md: always clear ->safemode when md_check_recovery gets the mddev lock.)
