This is a further updated version of the nproc v2 patchset[1] from advice given by Tejun Heo[2]. The main changes include:
* Switching from mm/page_counter (which is a memcg implementation feature) to a pid-controller-specific hierarchical charge/uncharge counter with limits implementation using atomic_long_t (which is also lockless as it is based on page_counter).
* Updates to the user-space interface to allow for the setting of no limit to the number of pids in a cgroup (-1 == unlimited) as well as renaming of the files and the removal of nproc.max_limit.
* The controller was renamed to `pids`.
