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

    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
    tip/tracing/ftrace-2


    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
