md/raid5: STRIPE_ACTIVE has lock semantics, add barriers All updates that occur under STRIPE_ACTIVE should be globally visible when STRIPE_ACTIVE clears. test_and_set_bit() implies a barrier, but clear_bit() does not. This is suitable for 3.1-stable. Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: NeilBrown <neilb@suse.de> Cc: stable@kernel.org
