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

This adds them per cpu in the directory:


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


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
