[PATCH 0/2] fdinfo shared stats

We had a request to add shared buffer stats to fdinfo for amdgpu and
while implementing that, Christian mentioned that just looking at
the GEM handle count doesn't take into account buffers shared with other
subsystems like V4L or RDMA.  Those subsystems don't use GEM, so it
doesn't really matter from a GPU top perspective, but it's more
correct if you actually want to see shared buffers.

  drm: update drm_show_memory_stats() for dma-bufs
  drm/amdgpu: add shared fdinfo stats
