Subject: [PATCH 00/16] block optimisation round
Date: Tue, 19 Oct 2021 22:24:09 +0100 [thread overview]
Message-ID: <cover.1634676157.git.asml.silence@gmail.com> (raw)
Jens tried out a similar series with some not yet sent additions:
8.2-8.3 MIOPS -> ~9 MIOPS, or 8-10%.
12/16 is bulky, but it nicely drives the numbers. Moreover, with
it we can rid of some not used anymore optimisations in
__blkdev_direct_IO() because it awlays serve multiple bios.
E.g. no need in conditional referencing with DIO_MULTI_BIO,
and _probably_ can be converted to chained bio.
Pavel Begunkov (16):
block: turn macro helpers into inline functions
block: convert leftovers to bdev_get_queue
block: optimise req_bio_endio()
block: don't bloat enter_queue with percpu_ref
block: inline a part of bio_release_pages()
block: clean up blk_mq_submit_bio() merging
blocK: move plug flush functions to blk-mq.c
block: optimise blk_flush_plug_list
block: optimise boundary blkdev_read_iter's checks
block: optimise blkdev_bio_end_io()
block: add optimised version bio_set_dev()
block: add single bio async direct IO helper
block: add async version of bio_set_polled
block: skip advance when async and not needed
block: optimise blk_may_split for normal rw
block: optimise submit_bio_checks for normal rw
