[PATCH] drm/amdgpu: add rcu_barrier after entity fini

To free the fence from the amdgpu_fence_slab, need twice call_rcu, to avoid the amdgpu_fence_slab_fini call kmem_cache_destroy(amdgpu_fence_slab) before kmem_cache_free(amdgpu_fence_slab, fence), add rcu_barrier after drm_sched_entity_fini. The kmem_cache_free(amdgpu_fence_slab, fence)'s call

Hi Oded, Thanks for working on this! The Makefile changes look good. Instead of checking and calling function pointers in amdgpu_amdkfd_... functions at runtime, couldn't you just define empty stub functions in amdgpu_amdkfd.h if KFD is not enabled? I think that would make the code shorter and

No, that spinlock is indeed incorrect. See even when we protect the spsc queue with a spinlock that doesn't make it correct. It can happen that the jobs pushed to the queue are reversed in their sequence order and that can cause severe problems in the memory management. Christian. Am
