Subject: [PATCH 0/6] some block optimisations
Date: Sat, 9 Oct 2021 13:25:37 +0100 [thread overview]
Message-ID: <cover.1633781740.git.asml.silence@gmail.com> (raw)
On top of perf-wip branch,
./io_uring -d32 -s32 -c32 -b512 -p1 /dev/nullb0
~3.3 MIOPS vs 3.5 MIOPS, so gives around extra ~4-5%.
The main part is caching struct block_device + some inlining.
Pavel Begunkov (6):
block: cache bdev in struct file for raw bdev IO
block: inline BDEV_I and friends
blk-mq: optimise *end_request non-stat path
block: inline hot paths of blk_account_io_*()
blk-mq: inline hot part of __blk_mq_sched_restart
block: convert ->bd_inode to container_of()
