Round two of this patchset to cleanup. Changes since the first posting: - Mark internal commands as REQ_OP_DRV_IN. Doesn't really matter what the data direction is, the important bit is that we need to ensure the request is seen as a passthrough. - Remove redundant active = 1 setting in mtip_commands_active(). - Utilize blk-mq timeout infrastructure, to avoid racing with cleanup. -- Jens Axboe
