[PATCH v2 13/13] cgroup: convert to kernfs

[Tejun Heo]

Hello,

Patch updated according to the review points and reports from the
bots.  Also, a different "name=" option handling bug is fixed.  Due to
the updates to patches earlier in the series, some of the previous
patches also need to be refreshed but as the refreshes don't involve
any meaningful changes, I'm not posting the updated versions here.
I'll post them together for the next revision.  However, all the git
branches have been updated with the latest versions of the patches.

Thanks!
