Subject[PATCH v8 0/4] cgroups: add pids subsystem
Date
This is an alternate version of the pids v7 patchset[1]. The main
difference is that this version doesn't add a new callback for
an association change during a fork -- it lets subsystems handle such
cases by themselves by allowing for a private pointer to be passed
around between the callbacks.

* Pass a cgroup_fork_state structure between the
cgroup_{can,cancel,post}_fork hooks which stores the private opaque
pointer for each subsystem. This allows for subsystems to decide which
(if any) state to save in the can_fork callback to refer back to in
the post_fork callback.

Aleksa Sarai (4):
cgroups: use bitmask to filter for_each_subsys
cgroups: replace explicit ss_mask checking with for_each_subsys_which
cgroups: allow a cgroup subsystem to reject a fork
cgroups: implement the PIDs subsystem
