    Subject[RFC PATCH v2 0/2] add nproc cgroup subsystem
    Date
    This is an updated version of the nproc patchset[1], in which the forking
    cleanup issue has been resolved by adding can_fork and cancel_fork
    callbacks to cgroup subsystems. The can_fork callback is run early
    enough that it doesn't get called after the "point of no return" where
    the process is exposed (which is when fork) is called, and cancel_fork
    is run during the cleanup of copy_process if the fork fails due to other
    reasons.
