X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=35d78c66969fbbb51046e9f251849cf54e9ed88c;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

md:Add place to update ->recovery_cp.

In resyncing, recovery_cp only updated when resync aborted or completed.
But in md drives,many place used it to judge.So add a place to update.
