md: raid-1/10: fix RW bits manipulation
Recently Jens has changed bio_rw_flagged() logic by following commit 1f98a13f623e0ef666690a18c1250335fc6d7ef1. Now it returns bool instead of int. This broke raid1/raid10 RW bits manipulation logic. One of visible result is BUG_ON triggering due to empty barrier here scsi_lib.c:1108 scsi_setup_fs_cmnd() Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: NeilBrown <neilb@suse.de>
