Hi Vivek,
I see the patch landed in drm-misc-next (504e2b4ab97a, tagged drm-misc-next-2026-04-20), which targets 7.2.
Since the patch has a Fixes: tag and Cc: stable, would it be possible to also cherry-pick it into drm-misc-next-fixes so it makes the 7.1 merge window that's closing soon?
I should have pushed the 3 udmabuf fixes to drm-misc-fixes instead of drm-misc-next but didn't do it because it was after RC6 and I didn't want to make any mistakes (accidentally). However, if the drm-misc maintainers (CC'd) are ok with it, I have no problem if they can cherry-pick these udmabuf patches to drm-misc-next-fixes so that they can make it into 7.1.
Thanks, Vivek
The bug is reproducible on current mainline and affects users with CONFIG_DMA_API_DEBUG_SG enabled.
