Hi Linus, here is a quick status update wrt. to regressions introduced in this cycle. This time hand-complied instead of from regzbot (I just broke something and lack time to fix it):
# Things that might or might not be a good reason for a -rc8
* Btrfs since v6.8-rc6 has a fiemap regression that "can actually have serious consequences", as mentioned in https://lore.kernel.org/linux-btrfs/cover.1709202499.git.fdmanana@suse.com/ The fixes in reply to that mail since Wednesday are in -next as 978b63f7464abc ("btrfs: fix race when detecting delalloc ranges during fiemap") and 1cab1375ba6d53 ("btrfs: reuse cloned extent buffer during fiemap to avoid re-allocations"), but not on the way to you afaics.
* A fix for Johan Hovold's last big Lenovo ThinkPad X13s regression (hard resets disconnecting external displays) is currently up for review and testing: https://lore.kernel.org/lkml/ZeyOmJLlBbwnmaJN@hovoldconsulting.com/
# Fixes for regressions from this cycle afaics unlikely to reach 6.8
* -next commit 3445139e3a594b ("Revert "Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"""), which reverts a commit from 6.8-rc1; Song thinks it's better to merge it for 6.9 and then backport to 6.8: https://lore.kernel.org/all/CAPhsuW51ND4qH4My8Uz1XaZSdvAjDR7eL7O-RLr5wKmFJA0XMQ@mail.gmail.com/ Report: https://lore.kernel.org/all/20240123005700.9302-1-dan@danm.net/
* -next commit 0d7dfc79fb9b4b ("drm/msm/a6xx: specify UBWC config for sc7180" No reply to my recent inquiry why this fix for a commit from this cycle was queued for 6.9: https://lore.kernel.org/all/4e55f6fd-8875-4a61-9070-f0ecad8082ea@leemhuis.info/ Report: https://gitlab.freedesktop.org/drm/msm/-/issues/49 and https://lore.kernel.org/all/85581fad-da8f-4550-a1c8-8f2996425dcd@lausen.nl/
# Regressions fixes sitting on the list awaiting review
* "drm/nouveau: keep DMA buffers required for suspend/resume", which fixes rendering freezes with multi-GPU setups: https://lore.kernel.org/dri-devel/20240229175822.30613-1-sidpranjale127@protonmail.com/
* "Fix divide-by-zero on DP unplug with nouveau" which fixes a divide error: https://lore.kernel.org/regressions/ZeoAPFIF6NClUl4P@debian.local/
* "u64_stats: fix u64_stats_init() for lockdep when used repeatedly in one file" fixes a lockdep splat https://lore.kernel.org/lkml/20240306111157.29327-1-petr@tesarici.cz/
# Regression reports where no fix is in sight afaics
* dmaengine: CPU stalls while loading bluetooth module https://lore.kernel.org/lkml/ZYhQ2-OnjDgoqjvt@wens.tw/ and https://lore.kernel.org/lkml/1553a526-6f28-4a68-88a8-f35bd22d9894@linumiz.com/ See also: https://lore.kernel.org/all/000001da7140%246a0f1570%243e2d4050%24@samsung.com/ Revert might be counter-productive.
* x86/mm/ident_map: kexec now leads to reboot https://lore.kernel.org/stable/3a1b9909-45ac-4f97-ad68-d16ef1ce99db@pavinjoseph.com/ https://lore.kernel.org/all/CAJbxNHe3EJ88ABB1aZ8bYZq=a36F0TFST1Fqu4fkugvyU_fjhw@mail.gmail.com/ A revert apparently could fix this.
Ciao, Thorsten
