    Subject[PATCH v2 0/8] [GIT PULL] ring-buffer: various updates


    Thomas suggested that I try to fine grain the big patch in this series.
    It contained some minor clean ups, so I pulled them out of that patch.
    But that patch is still a bit big. Just because it changes the fact
    that the ring buffer functions can now accept a time extend as well
    as a data event. Those changes were rather trivial though.

    Please pull the latest tip/perf/ringbuffer-2 tree, which can be found at:


    Steven Rostedt (8):
    ring-buffer: Make write slow path out of line
    ring-buffer: Pass timestamp by value and not by reference
    ring-buffer: Pass delta by value and not by reference
    ring-buffer: Remove ring_buffer_event_time_delta()
    ring-buffer: Bind time extend and data events together
    ring-buffer: Remove condition to add timestamp in fast path
    ring-buffer: Micro-optimize with some strategic inlining
    ring-buffer: Remove unused macro RB_TIMESTAMPS_PER_PAGE
