The BO can then be evictedwithout suspending the user queues of the file, which keep accessing itthrough mappings that are only marked for update.\nSeen on navi31 with a SDMA user queue: a BO opened twice in the samefile (GEM_FLINK + GEM_OPEN) loses its eviction fence when the secondhandle is closed (traced attach/detach of the fence):\n  attach bo=ffff8c78a6c84c00  GEM_CLOSE handle=7  detach bo=ffff8c78a6c84c00\nwhile handle 6 and the mapping are still in use.\nOnly detach the fence when the last reference to the bo_va goes away,matching amdgpu_gem_object_open(), which attaches it only when thebo_va is created. With this the fence stays until the file is closed.\n(cherry picked from commit
