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


Ingo,

Here's some udpates to the ring buffer. Mainly, exporting the
counters (and adding new ones) to userspace. We keep track of entries
and overruns but currently they only get displayed with the latency
format.

This adds them per cpu in the directory:

  /debugfs/tracing/per_cpu/cpuX/stats


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

  git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git
tip/tracing/ftrace


Steven Rostedt (3):
      ring-buffer: add counters for commit overrun and nmi dropped entries
      tracing: export stats of ring buffers to userspace
      ring-buffer: make cpu buffer entries counter atomic
