Subject: [PATCH RFC 0/3] Fix regression bugs
Date: Mon, 19 Feb 2024 14:26:18 +0800 [thread overview]
Message-ID: <20240219062621.92960-1-xni@redhat.com> (raw)
Hi all
Sorry, I know this patch set conflict with Yu Kuai's patch set. But
I have to send out this patch set. Now we're facing some deadlock
regression problems. So it's better to figure out the root cause and
fix them. But Kuai's patch set looks too complicate for me. And like
we're talking in the emails, Kuai's patch set breaks some rules. It's
not good to fix some problem by breaking the original logic. If we really
need to break some logic. It's better to use a distinct patch set to
describe why we need them.
This patch is based on linus's tree. The tag is 6.8-rc5. If this patch set
can be accepted. We need to revert Kuai's patches which have been merged
in Song's tree (md-6.8-20240216 tag). This patch set has three patches.
The first two resolves deadlock problems. With these two patches, it can
resolve most deadlock problem. The third one fixes active_io counter bug.
I have run lvm2 regression test. lvconvert-raid-reshape.sh is failed. This
patch set doesn't plan to fix it. Kuai's patch set has a patch which should
fix it. And there are other 4 failed cases:
shell/dmsetup-integrity-keys.sh
shell/lvresize-fs-crypt.sh
shell/pvck-dump.sh
shell/select-report.sh
