    Subject[PATCH 0/3] [GIT PULL] tracing/ringbuffer: updates for tip


    Here's some udpates to the ring buffer. Mainly, exporting the

    Please pull the latest tip/tracing/ftrace tree, which can be found at:


    Steven Rostedt (3):

    tracing: export stats of ring buffers to userspace
    ring-buffer: make cpu buffer entries counter atomic
