Subject: [dm-devel] [PATCH 5.20 v2 0/3] block/dm: add bio_rewind to improve DM requeue
Date: Wed, 29 Jun 2022 17:55:10 -0400 [thread overview]
Message-ID: <20220629215513.37860-1-snitzer@kernel.org> (raw)
Hi,
This v2 is the by-product of my having picked up v1's patch 2+3 and
folding them (into patch 1 of this v2 series). So patch 1 of this v2
is settled and will be merged into 5.20.
Patches 2 and 3 are the result of me having gone over the v1 code. I
folded in the copy-n-paste bugfix that Eric Biggers kindly pointed out
in v1. I also updated patch headers and code comments for clarity. And
I also renamed some variables, tweaked some style knits (subjective
but whatever).
This code is available in linux-dm.git's 'dm-5.20' branch:
https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-5.20
Which is based on Jens's for-5.20/block
I'll obviously rebase 'dm-5.20' ontop of Jens's branch if/when he
picks up patch 2 in this series.
This code is passing all my tests so far but testing is ongoing.
All comments welcome.
ps. I was told Kent had replied to the v1 thread while I was working
on this v2, I kept focus on finishing this v2. I'll check my email in
a bit.
