    [PATCH] per-task-delay-accounting: taskstats interface · c757249a
    Shailabh Nagar authored
    Create a "taskstats" interface based on generic netlink (NETLINK_GENERIC
    family), for getting statistics of tasks and thread groups during their
    lifetime and when they exit.  The interface is intended for use by multiple
    accounting packages though it is being created in the context of delay
    accounting.
    
    This patch creates the interface without populating the fields of the data
    that is sent to the user in response to a command or upon the exit of a task.
    Each accounting package interested in using taskstats has to provide an
    additional patch to add its stats to the common structure.
