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

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:


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
