Merge branch 'for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo: "cgroup file type addition / removal is updated so that file types are added and removed instead of individual files so that dynamic file type addition / removal can be implemented by cgroup and used by controllers. blkio controller changes which will come through block tree are dependent on this. Other changes include res_counter cleanup and disallowing kthread / PF_THREAD_BOUND threads to be attached to non-root cgroups. There's a reported bug with the file type addition / removal handling which can lead to oops on cgroup umount. The issue is being looked into. It shouldn't cause problems for most setups and isn't a security concern." Fix up trivial conflict in Documentation/feature-removal-schedule.txt * 'for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: (21 commits) res_counter: Account max_usage when calling res_counter_charge_nofail() res_counter: Merge res_counter_charge and res_counter_charge_nofail cgroups: disallow attaching kthreadd or PF_THREAD_BOUND threads cgroup: remove cgroup_subsys->populate() cgroup: get rid of populate for memcg cgroup: pass struct mem_cgroup instead of struct cgroup to socket memcg cgroup: make css->refcnt clearing on cgroup removal optional cgroup: use negative bias on css->refcnt to block css_tryget() cgroup: implement cgroup_rm_cftypes() cgroup: introduce struct cfent cgroup: relocate __d_cgrp() and __d_cft() cgroup: remove cgroup_add_file[s]() cgroup: convert memcg controller to the new cftype interface memcg: always create memsw files if CONFIG_CGROUP_MEM_RES_CTLR_SWAP cgroup: convert all non-memcg controllers to the new cftype interface cgroup: relocate cftype and cgroup_subsys definitions in controllers cgroup: merge cft_release_agent cftype array into the base files array cgroup: implement cgroup_add_cftypes() and friends cgroup: build list of all cgroups under a given cgroupfs_root cgroup: move cgroup_clear_directory() call out of cgroup_populate_dir() ...
