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 [1] https://lore.kernel.org/linux-raid/e5e8afe2-e9a8-49a2-5ab0-958d4065c55e@xxxxxxxxxx/ [2] https://lore.kernel.org/linux-raid/20240123005700.9302-1-dan@xxxxxxxx/ [3] 87165c64fe1a in linux-6.7.y branch.
