Subject: [GIT PULL] md-6.9 20240305
Date: Tue, 5 Mar 2024 23:42:23 +0000 [thread overview]
Message-ID: <1C22EE73-62D9-43B0-B1A2-2D3B95F774AC@fb.com> (raw)
Hi Jens,
Please consider pulling the following fixes for md-6.9 on top of your
for-6.9/block branch. This set fixes two issues:
1. dmraid regression since 6.7 kernels. This issue was initially
reported in [1]. This set of fix has been reviewed and tested by
md and dm folks.
2. raid5 hang since 6.7 kernel, reported in [2]. We haven't got a
better fix for this issue yet. This revert is a workaround. It has
been applied to 6.7 stable kernels [3], and proved to be affective.
We will look more into this issue for a better fix.
Note: Some recent fixes were shipped via the md-6.8 branch, so the
md-6.9 branch doesn't have all the fixes. I tested that there is no
conflict between these fixes and those shipped earlier. I run the
tests with upstream kernel and changes in block tree and md tree
(v6.8-rc7 + for-6.9/block + md-6.9).
Thanks,
Song
