Hi all,
I've started this a while ago, with the idea to move shmem helpers over to dma_resv_lock. Big prep work for that was to untangle the layering between functions called by drivers, and functions used to implement drm_gem_object_funcs.
I didn't ever get to the locking part, but I think the cleanup here are worth it stand-alone still.
Comments, review and testing very much welcome.
Cheers, Daniel
