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