FYI, here is the latest revised patch: https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=dm-4.6&id=a5b835282422ec41991c1dbdb88daa4af7d166d2 (revised patch header and fixed a thinko in the dm.c:rq_completed() change from the RFC patch I posted earlier)
Hi Mike, So I gave your patches a go (dm-4.6) but I still don't see the improvement you reported (while I do see a minor improvement). null_blk queue_mode=2 submit_queues=24 dm_mod blk_mq_nr_hw_queues=24 blk_mq_queue_depth=4096 use_blk_mq=Y I see 620K IOPs on dm_mq vs. 1750K IOPs on raw nullb0. Is there something I'm missing? -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
