I think the changes to the hotpaths of the slab allocators increasing register pressure in some of the hotttest paths of the kernel are problematic. Its better to do the allocation properly in the task context to which it is finally charged. There may be other restrictions that emerge from other fields in the task_struct that also may influence allocation and reclaim behavior. It is cleanest to do this in the proper task context instead of taking a piece (like the cgroup) out of context.
