I found some small differences in the first few patches. I haven't
progressed past patch 13 yet, though.

Jason, patches 5 through 12 are general cleanups in preparation for
vk-dma-buf support. Those cleanups, in my opinion, can and should land
before the actual vk-dma-buf patches, and could land now (after review
and testing). What do you think? I don't expect those patches to change,
even as the rest of the patch series evolves.
