cgroup_subsys->disabled and cgroup_on_dfl() tests are likely to be used in hot paths and seldom change. The former is set once during boot and the latter only when a controller is migrated between the default hierarchy and traditional ones. This patchset makes these tests static_key based and contains the following four patches. 0001-jump_label-make-static_key_enabled-work-on-static_ke.patch 0002-cgroup-implement-static_key-based-cgroup_subsys_enab.patch 0003-cgroup-replace-cgroup_subsys-disabled-tests-with-cgr.patch 0004-cgroup-replace-cgroup_on_dfl-tests-in-controllers-wi.patch 0001 is a prep patch in jump_label. 0002 adds the needed static_keys. 0003-0004 convert the existing usages and drop the old tests. This patchset is on top of v4.3-rc1 and is availalbe in the following git branch. git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-jump-labels diffstat follows.
