I see two small memory leaks on a Fedora 41 desktop with a custom built
kernel @ commit:
27d4815149ba drm/sched: Group exported prototypes by object type
GPU is an RTX 5000 Ada
The leaks are there immediately after booting the machine. They don't
seem to reoccur, although I have not verified this very strictly.
