Subject: bio splitting cleanups v2
Date: Sat, 23 Jul 2022 08:28:10 +0200 [thread overview]
Message-ID: <20220723062816.2210784-1-hch@lst.de> (raw)
Hi Jens,
this series has two parts: the first part moves the ->bio_split
bio_set to the gendisk as it only is used for file system style I/O.
The other patches reshuffle the bio splitting code so that in the future
blk_bio_segment_split can be used to split REQ_OP_ZONE_APPEND bios
under file system / remapping driver control. I plan to use that in
btrfs in the next merge window.
Changes since v1:
- drop a bogus patch
- fix a comment typo
- fix a commit log typo
- clean up the blk_queue_split calling convention and name
