Hello Jens, The 1st two fixes ublk_abort_requests(), and adds comment on handling ubq->canceling. The 3rd ~ 5th patches are cleanup. The 6th and 7th are zc-followup. The 8th & 9th patch implements ->queue_rqs() and improves IOPS by > 10%. The last two patches are self-test for ->queue_rqs() & segment parameter change. V2: - use io_uring_cmd_to_pdu() (Uday) - improve zc document (Caleb) - consolidate segment parameter interface (Caleb) - add reviewed-by - add one fix and comment on ubq->canceling - fix one hang bug in V2 Ming Lei (11): ublk: make sure ubq->canceling is set when queue is frozen ublk: comment on ubq->canceling handling in ublk_queue_rq() ublk: remove two unused fields from 'struct ublk_queue' ublk: add helper of ublk_need_map_io() ublk: call io_uring_cmd_to_pdu to get uring_cmd pdu ublk: add segment parameter ublk: document zero copy feature ublk: implement ->queue_rqs() ublk: rename ublk_rq_task_work_cb as ublk_cmd_tw_cb selftests: ublk: add more tests for covering MQ selftests: ublk: add test for checking zero copy related parameter Documentation/block/ublk.rst | 35 ++- drivers/block/ublk_drv.c | 214 ++++++++++++++---- include/uapi/linux/ublk_cmd.h | 25 ++ tools/testing/selftests/ublk/Makefile | 4 + tools/testing/selftests/ublk/null.c | 11 +- tools/testing/selftests/ublk/test_common.sh | 6 + .../testing/selftests/ublk/test_generic_02.sh | 44 ++++ .../testing/selftests/ublk/test_generic_03.sh | 28 +++ tools/testing/selftests/ublk/test_loop_01.sh | 14 +- tools/testing/selftests/ublk/test_loop_03.sh | 14 +- tools/testing/selftests/ublk/test_loop_05.sh | 28 +++ .../testing/selftests/ublk/test_stress_01.sh | 6 +- .../testing/selftests/ublk/test_stress_02.sh | 6 +- .../testing/selftests/ublk/test_stripe_01.sh | 14 +- .../testing/selftests/ublk/test_stripe_03.sh | 30 +++ 15 files changed, 397 insertions(+), 82 deletions(-) create mode 100755 tools/testing/selftests/ublk/test_generic_02.sh create mode 100755 tools/testing/selftests/ublk/test_generic_03.sh create mode 100755 tools/testing/selftests/ublk/test_loop_05.sh create mode 100755 tools/testing/selftests/ublk/test_stripe_03.sh -- 2.47.0
