Subject[GIT PULL] cgroup changes for v4.5-rc1
Hello, Linus.

cgroup changes for v4.5-rc1.

* cgroup v2 interface is now official. It's no longer hidden behind a
devel flag and can be mounted using the new cgroup2 fs type.
Unfortunately, cpu v2 interface hasn't made it yet due to the
discussion around in-process hierarchical resource distribution and
only memory and io controllers can be used on the v2 interface at
the moment.

* The existing documentation which has always been a bit of mess is
relocated under Documentation/cgroup-legacy/.
Documentation/cgroup.txt is added as the authoritative documentation
for the v2 interface.

* Some features are added through for-4.5-ancestor-test branch to
enable netfilter xt_cgroup match to use cgroup v2 paths. The actual
netfilter changes will be merged through the net tree which pulled
in the said branch.

* Various cleanups.

Thanks.
