I think a general:

MEMORY MANAGEMENT [RUST]

works better here as it ought to (at least for the time being) cover off all
rust mm stuff.

I wonder if we should have Andrew as a co-maintainer here so people also
send to Andrew also for merge? (and obviously as the mm maintainer he may
have commentary).

Am happy to be a reviewer this is fine!

I am sure Liam is also, but of course he can comment himself :)

Probably need these here too if Andrew is taking in his tree:

W:	http://www.linux-mm.org
T:	git git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

But in general with tweaks I am happy for this to be added to MAINTAINERS
_personally_, am I but a minor figure however, it is up to Andrew
ultimately :)
