drbd: If we detect late that IO got frozen, retry after we thawed. If we detect late (= after grabing mdev->req_lock) that IO got frozen, we return 1 to generic_make_request(), which simply will retry to make a request for that bio. In the subsequent call of generic_make_request() into drbd_make_request_26() we sleep in inc_ap_bio().
