Merge branch 'jani-rest' into docs-next
Patch series from Jani Nikula:
> Jon, I was hoping we could consider nudging things forward a bit in the
> kernel-doc and docproc reStructuredText front already in 4.7. I know
> it's a bit close to the merge window, but this should not interfere with
> anything else, and some of it are just trivial cleanups that I've been
> carrying around locally.
>
> Obviously this doesn't actually add anything that uses them yet, but I
> think it would be helpful to have some common base in to ease
> collaboration.

-Kernel memory won't be accounted at all until limit on a group is set. This

-cannot be set if the cgroup have children, or if there are already tasks in the

-When use_hierarchy == 1 and a group is accounted, its children will

+Kernel memory accounting is enabled for all memory cgroups by default. But

Kernel memory limits are not imposed for the root cgroup. Usage for the root
cgroup may or may not be accounted. The memory used is accumulated into
