Subject: [PATCH V2 0/4] Fix dmraid regression bugs
Date: Fri,  1 Mar 2024 23:21:24 +0800	[thread overview]
Message-ID: <20240301152128.13465-1-xni@redhat.com> (raw)

Hi all

This patch set tries to fix dmraid regression problems we face
recently. This patch is based on song's md-6.8 branch. 

This patch set has four patches. The first two patches revert two patches.
The third one and the fourth one resolve deadlock problems.

I have run lvm2 regression test 5 times. There are 4 failed cases:
shell/dmsetup-integrity-keys.sh
shell/lvresize-fs-crypt.sh
shell/pvck-dump.sh
shell/select-report.sh

And lvconvert-raid-reshape.sh can fail sometimes. But it fails in 6.6
kernel too. So it can return back to the same state with 6.6 kernel.

V2:
It doesn't revert commit 82ec0ae59d02
("md: Make sure md_do_sync() will set MD_RECOVERY_DONE")
It doesn't clear MD_RECOVERY_WAIT before stopping dmraid

Xiao Ni (4):
  md: Revert "md: Don't register sync_thread for reshape directly"
  md: Revert "md: Don't ignore suspended array in md_check_recovery()"
  md: Set MD_RECOVERY_FROZEN before stop sync thread
  md/raid5: Don't check crossing reshape when reshape hasn't started
