raid5: remove unnecessary bitmap write optimization Neil pointed out the bitmap write optimization in handle_stripe_clean_event() is unnecessary, because the chance one stripe gets written twice in the mean time is rare. We can always do a bitmap_startwrite when a write request is added to a stripe and bitmap_endwrite after write request is done. Delete the optimization. With it, we can delete some cases of device_lock. Signed-off-by: Shaohua Li <shli@fusionio.com> Signed-off-by: NeilBrown <neilb@suse.de>
