[Libcg-devel] [PATCH 0/4] Add cgroup v2 support to cgget and cgset

[Tom H. <tom...@or...>]

This patchset adds cgroup v2 support to cgroup_init() and
cg_test_mounted_fs().  For simple cgroup interfaces like cgget
and cgset, these were the only changes necessary to add cgroup
v2 support to those tools.

I tested the changes by hand on a cgroup v1 mount, a cgroup v2
mount, and the cgroup v2 unified hierarchy.  I have started
adding cgroup v2 support to the automated test suite, but a lot
of work remains.

Since the tests have been split into a separate git repo, those
patches will come out in a separate patchset.

$ sudo ./cgset -r cpu.weight=999 foo
$ sudo ./cgget -r cpu.weight foo
foo:
cpu.weight: 999

Automated test results are here:

Code coverage increased by 0.8% and is available here:
