Subject: md: cancel check/repair requests when recovery is needed
X-Git-Tag: firefly_0821_release~18254^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=56ac36d722d0d27c03599d1245ac0ab59e474e5c;p=firefly-linux-kernel-4.4.55.git

md: cancel check/repair requests when recovery is needed

If a 'repair' is requested when an array is in a position to 'recover' raid1
will perform the repair while md believes a recovery is happening.  Address
this at both ends, i.e. cancel check/repair requests upon detecting a
recover condition and do not call ->spare_active after completing a
check/repair.
