Subject: [PATCH v3 0/2] cgroup: add pids subsystem
Date: Thu, 5 Mar 2015 07:23:17 +1100 [thread overview]
Message-ID: <1425500599-21676-1-git-send-email-cyphar@cyphar.com> (raw)
In-Reply-To: <1424660891-12719-1-git-send-email-cyphar@cyphar.com>
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`.
