Subject: [RFC PATCH 0/4] cgroups: Start a basic rlimit subsystem

This starts a basic rlimit cgroup subsystem with only the
equivalent of RLIMIT_NPROC yet. This can be useful to limit
the global effects of a local fork bomb for example (local
in term of a cgroup).

The thing is further expandable to host more general resource
limitations in the scope of a cgroup.

Frederic Weisbecker (4):
  cgroups: Allow a cgroup subsys to reject a fork
  cgroups: Add res_counter_write_u64() API
  cgroups: New resource counter inheritance API
  cgroups: Add an rlimit subsystem
