Since commit 01e99aec 'blk-mq: insert passthrough request into hctx->dispatch directly', passthrough request should not appear in IO-scheduler any more, so blk_rq_is_passthrough checking in addon IO schedulers is redundant. (Notes: this patch passes generic IO load test with hdds under SAS controller and hdds under AHCI controller but obviously not covers all. Not sure if passthrough request can still escape into IO scheduler from blk_mq_sched_insert_requests, which is used by blk_mq_flush_plug_list and has lots of indirect callers.) Signed-off-by:
