When trying to do a rather aggressive test of igt's "xe_module_load
--r reload" with a full desktop environment and game running I noticed
a few OOPSes when dereferencing freed pointers, related to
framebuffers and property blobs after the compositor exits.
Solve this by guarding the freeing in drm_file with drm_dev_enter/exit,
and immediately put the references from struct drm_file objects during
drm_dev_unplug().
With this patch in v6.18.20, I get the warning backtraces below.
The backtraces are gone with the patch reverted.

That's a weird bug. What framebuffer driver is providing the simple fb?
I have no idea, sorry. I did not touch that code. It is pure upstream with no
downstream drivers. The configuration is derived from the standard Ubuntu
configuration file. The configuraton file includes
CONFIG_FB_NVIDIA=m
CONFIG_FB_NVIDIA_I2C=y
and
CONFIG_DRM_NOUVEAU=m
CONFIG_NOUVEAU_DEBUG=5
CONFIG_NOUVEAU_DEBUG_DEFAULT=3
# CONFIG_NOUVEAU_DEBUG_MMU is not set
# CONFIG_NOUVEAU_DEBUG_PUSH is not set
CONFIG_DRM_NOUVEAU_BACKLIGHT=y
# CONFIG_DRM_NOUVEAU_SVM is not set
CONFIG_DRM_NOUVEAU_CH7006=m
CONFIG_DRM_NOUVEAU_SIL164=m
fb related log messages are

I can send you the complete dmesg and configuration file if it helps.
Thanks,
