[PATCH 0/1] Fix use-after-free on framebuffers and property blobs when calling drm_dev_unplug

[Maarten Lankhorst <dev@lankhorst.se>]

I tried to see what happened with xe_module_unload --r reload on a fully
running system, and came across these bugs in the kernel. Even after
these fixes I still see a hang when reloading, related to cgroups, so
likely some more fixes are needed to address those.

Should this patch have a fixes tag or cc stable patch?
