Hi steven,

This patchset contain:
1) event tracing expose work (v2)
   this expose work rewrited compare with v1, new implementation
   is based on multi-instances buffer work, it also integrate syscall
   tracing code to use same event backend store mechanism.
   The change include patch 1-7(patch 2 also fix a long-term minor bug)

2) some cleanup
   This include patch 8-12.

3) patch 13 fix libtraceevent warning

4) patch 14 fix a regression bug of perf function tracing
   This patch also need send to stable tree.

Note that these patches is based on latest linux-trace git tree:
(on top of multi-instances buffer implementation)

    git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git
    tip/perf/core

All patches pass basic testing.
