In the Linux kernel, the following vulnerability has been resolved:
drm/xe/guc: Keep scheduler timeline name alive
The scheduler keeps a pointer to the timeline name, but q->name
is freed with the exec queue while scheduler fences can still
reference it.
Store the name in struct xe_guc_exec_queue so it shares
the scheduler's RCU-deferred lifetime.
(cherry picked from commit 41075f0eb5dcbd3b065d15f15ef7bbe9315188e8)
