Re: [PATCH] drm/nouveau: Fix race in nouveau_sched_fini()

nouveau_sched_fini() uses a memory barrier before wait_event(). wait_event(), however, is a macro which expands to a loop which might check the passed condition several times. The barrier would only take effect for the first check.

Replace the barrier with a function which takes the spinlock.
