Subject: [GIT PULL] md-6.8 20240305
Date: Tue, 5 Mar 2024 18:47:17 +0000 [thread overview]
Message-ID: <2FCF4E06-B33B-44A8-95D7-8BA481313BB8@fb.com> (raw)
Hi Jens,
Please consider pulling the following fixes for md-6.8 on top of your
block-6.8 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.
We understand this is really last minute for the 6.8 release. But based
on the data we have, these changes are safe and fix issues in the 6.8
kernel.
Thanks,
Song
