Subject[PATCH 0/5] cache request_queue pointer
Date
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
