[PATCHSET] cgroup: misc fixes and cleanups

[Tejun Heo]

Hello,

This patchset contains the following six patches.  The first one is a
fix but should be safe to route through for-4.6.  The rest are misc
cleanups and improvements which don't cause notable behavior changes.

 0001-cgroup-fix-error-return-value-of-cgroup_addrm_files.patch
 0002-Revert-cgroup-add-cgroup_subsys-css_e_css_changed.patch
 0003-cgroup-s-child_subsys_mask-subtree_ss_mask.patch
 0004-cgroup-convert-for_each_subsys_which-to-do-while-sty.patch
 0005-cgroup-use-do_each_subsys_mask-where-applicable.patch
 0006-cgroup-make-cgroup-subsystem-masks-u16.patch

The patchset based on top of cgroup/for-4.6 223ffb29f972 ("cgroup:
provide cgroup_nov1= to disable controllers in v1 mounts") and is
available in the following git branch.

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-misc

diffstat follows.  I'll pull in the branch into cgroup/for-4.6
soonish.
