I made a preliminary port of the DRM-SHMEM shrinker on top of the the
latest version of dma-buf locking convention and yours LRU patches. It
all works good, the only thing that is missing for the DRM-SHMEM
shrinker is the drm_gem_lru_remove_locked().

What about to add a locked variant of drm_gem_lru_remove()?
