Subject: [PATCH v2 0/3] on top of for-5.16/block
Date: Wed, 13 Oct 2021 09:57:10 +0100 [thread overview]
Message-ID: <cover.1634115360.git.asml.silence@gmail.com> (raw)
./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.
v2: without applied patches, merge previous 6/6 into the second patch
get rid of helpers (Jens, Christoph)
kill bdev_inode and move inode into bdev (Christoph)
Pavel Begunkov (3):
block: cache bdev in struct file for raw bdev IO
block: don't hide inode from block_device users
blk-mq: optimise *end_request non-stat path
