Subject[PATCH 00/11] [GIT PULL] tracing/ring-buffer: various updates


I rebased again (using ftrace-2 now) and made some minor clean
ups to the patches, as well as added several new ones.

The last patch of the series adds a benchmark/tester for the
ring buffer. It creates a producer and consumer and measures the time
and number of entries recorded. It prints out the results via
pr_info every 10 seconds.

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


Steven Rostedt (10):
ring-buffer: export symbols
ring-buffer: add counters for commit overrun and nmi dropped entries
tracing: export stats of ring buffers to userspace
ring-buffer: convert cpu buffer entries to local_t
ring-buffer: record page entries in buffer page descriptor
ring-buffer: have read page swap increment counter with page entries
ring-buffer: disable writers when resetting buffers
tracing: use proper export symbol for tracing api
ring-buffer: move big if statement down
ring-buffer: add benchmark and tester

Tim Abbott (1):
ftrace: use .sched.text, not .text.sched in
