ACK, although I had quite the rough time applying this after the
conflicts with virDomainSetMemoryFlags. I ended up shuffling things to
match shuffles earlier in the series.

Wrong case. How'd you test this?

SET_MEMORY_FLAGS beat you to 204; you get 205 and 206.
Hmm, I guess that completes my review, so I'm pushing it. Thanks again
for the work!
However, I do have a parting comment that this was a _lot_ of code
duplication; if we ever add another cgroup tunable, it would be worth
the time to first factor out the common elements into something that
memtune, blkio, and that new cgroup tunable could share. For example,
we don't need three copies of the union for i/ui/l/ul/d/b - that should
be something easy to share between tunables.
