Cache request_queue in bdev and replace two derefs in bdev->bd_disk->queue with bdev->bd_queue. Benchmarking with nullblk gave me around +1% to peak perf. All patches are self contained and don't rely on others from the set including 1/5 and can be taken separately. And some changes go in separate patches to minimise conflicts. When we agree on the approach, I'll send the rest converting some other spots out of block. note: based on for-5.16/block-io_uring Pavel Begunkov (5): block: cache request queue in bdev block: use bdev_get_queue() in bdev.c block: use bdev_get_queue() in bio.c block: use bdev_get_queue() in blk-core.c block: convert the rest of block to bdev_get_queue block/bdev.c | 9 +++++---- block/bio-integrity.c | 2 +- block/bio.c | 10 +++++----- block/blk-cgroup.c | 16 ++++++++-------- block/blk-core.c | 10 +++++----- block/blk-crypto.c | 2 +- block/blk-iocost.c | 12 ++++++------ block/blk-merge.c | 2 +- block/blk-mq.c | 2 +- block/blk-throttle.c | 2 +- block/genhd.c | 8 +++++--- block/partitions/core.c | 4 ++-- include/linux/blk_types.h | 1 + include/linux/blkdev.h | 2 +- 14 files changed, 43 insertions(+), 39 deletions(-) -- 2.33.0
