Subject: [PATCH 00/11] [GIT PULL] tracing/ring-buffer: various updates
Date: Wed, 06 May 2009 00:21:01 -0400	[thread overview]
Message-ID: <20090506042101.231470089@goodmis.org> (raw)


Ingo,

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:

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

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 recordmcount.pl
