    Subject[PATCH 0/4] [GIT PULL] memory saving ring buffer for tip/tracing/ftrace
    Ingo,

    This patch series implements a better memory management by the
    ring buffer. It only allocates the buffers for the online CPUS, as well
    as keeps the buffers to a minimum size until they are used.

    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 (4):
    tracing: keep ring buffer to minimum size till used
    tracing: expand the ring buffers when an event is activated
    tracing: fix trace_wait to know to wait on all cpus or just one
    ring-buffer: only allocate buffers for online cpus
