    Subject[PATCH 0/4] Tracepoints for deadline scheduler
    Date
    Deadline tasks behave differently of other tasks because deadline
    task's also depend on their period, deadline and runtime.

    Hence, the well known sched:sched_wakeup and sched:sched_switch
    tracepoints are not always enough to precisely explain the behavior of a
    deadline task with respect to the task's period, deadline and runtime
    consumption.

    This patch series implements tracepoints for the following deadline
    scheduler points of interest:

    - sched:sched_deadline_replenish: Informs the periodic runtime
    replenishment of a deadline task.

    - sched:sched_deadline_yield: Informs that a deadline task called
    sched_yield(), and will wait for the next period.

    - sched:sched_deadline_throttle: Informs that a task consumed all its
    available runtime and was throttled.

    - sched:sched_deadline_block: Informs that a deadline task went to sleep
    waiting to be awakened by another task.

    Daniel Bristot de Oliveira (3):
    sched: Move deadline container_of() helper functions into sched.h
    sched/deadline: Tracepoints for deadline scheduler
    tools lib traceevent: Implements '%' operation

    Steven Rostedt (Red Hat) (1):
    tracing: Add __print_ns_to_secs() and __print_ns_without_secs()
    helpers
