Interesting. I have a CPU with Intel Iris Pro graphics, which has 128MB of on-die eDRAM, which appears as L4 cache and which I assume can be used as both VRAM and cache.

I wonder if this is useful to me in terms of allocating/using it for the latter?

At a guess, because KernelNewbies.org is maintained by volunteers who may have had their own reasons for why they didn't have time to finish the 4.9 page?

From the original post:

> On the whole, 4.10 didn't end up as small as it initially looked. After the huge release that was 4.9

4.9 was "huge". I guess volunteers trying to cook up a quick summary may have given up on it :)

4.9 was expected to be a long-term support release, so there was strong motivation to complete and merge anything that was almost ready. The maintainers knew this would happen and threatened to hold off on making a new longterm release until 4.10 or later if 4.9 ended up too full of half-baked code, but it seems to have mostly worked out as just a large release that is now officially the most recent longterm branch.
