All the prerequisite patches are now available in cgroup/for-4.6 branch.
git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-4.6
If the perf_event changes look okay, we can either apply the first patch to cgroup/for-4.6, pull that into perf tree and aply the perf change there or route both through cgroup tree. Ideas?
Thanks.
