[PATCH] device-mapper raid1: drop mark_region spinlock fix
The spinlock region_lock is held while calling mark_region which can sleep. Drop the spinlock before calling that function. A region's state and inclusion in the clean list are altered by rh_inc and rh_dec. The state variable is set to RH_CLEAN in rh_dec, but only if 'pending' is zero. It is set to RH_DIRTY in rh_inc, but not if it is already so. The changes to 'pending', the state, and the region's inclusion in the clean list need to be atomicly.
