Cpuset hardwall flag: switch cpusets to use the bulk cgroup_add_files() API
Currently the cpusets mem_exclusive flag is overloaded to mean both "no-overlapping" and "no GFP_KERNEL allocations outside this cpuset". These patches add a new mem_hardwall flag with just the allocation restriction part of the mem_exclusive semantics, without breaking backwards-compatibility for those who continue to use just mem_exclusive. Additionally, the cgroup control file registration for cpusets is cleaned up to reduce boilerplate. This patch: This change tidies up the cpusets control file definitions, and reduces the amount of boilerplate required to add/change control files in the future.
