Subject: [PATCH] MD: not clear ->safemode for external metadata array
References: bnc#1060662
Patch-mainline: 4.12.9
Git-commit: afc1f55ca44e257f69da8f43e0714a76686ae8d1
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.)
