Since I fat-fingered the previous posting of v2, here's a v2a that is what v2 should have been. No changes since v2, just for easier review. Sorry about that. To recap, changes since v1: - 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
