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.
