Subject: move more work to disk_release v4
Date: Tue, 8 Mar 2022 06:51:46 +0100 [thread overview]
Message-ID: <20220308055200.735835-1-hch@lst.de> (raw)
Hi all,
this series resurrects and forward ports ports larger parts of the
"block: don't drain file system I/O on del_gendisk" series from Ming,
but does not remove the draining in del_gendisk, but instead the one
in the sd driver, which always was a bit ad-hoc. As part of that sd
and sr are switched to use the new ->free_disk method to avoid having
to clear disk->private_data and the way to lookup the SCSI ULP is
cleaned up as well.
The latest version only has cosmetic changes and plenty of rewiews and
should be ready to merge now.
Git branch:
git://git.infradead.org/users/hch/block.git freeze-5.18
Gitweb:
http://git.infradead.org/users/hch/block.git/shortlog/refs/heads/freeze-5.18
Changes since v3:
- make use of existing local variables and helpers
- update a few commit logs
- better document the disk_dev in the sd driver
Changes since v2:
- handle the weird dm-multipath flush sequence corner case when
assinging rq->part
Changes since v1:
- fix a refcounting bug in sd
- rename a function
