“For those wondering: It seems the patch has now been integrated mainline (it is part of 5.11-rc6) and should land in Linux 5.11. Thanks @karolherbst and @skeggsb! Hope that it qualifies for the stable kernel branches as well. ( Bastian Beranek )”
“Quick note: @bastianbeischer’s patch is backported to stable kernel >= v5.10.13: (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/gpu/drm/nouveau?h=v5.10.13&id=e4d2a196fdc5f7eeab21d3d6a27566f3dc1f4d60)”
