Hello,

This patchset add 'function-fork' option to function tracer which
makes pid filter to be inherited like 'event-fork' does.  During the
test, I found a bug of pid filter on an instance directory.  The patch
1 fixes it and maybe it should go to the stable tree.

The function-fork option is disabled by default as event-fork does,
but we might consider changing the default since it seems to be more
natural from an user's perspective IMHO.

The code is also available at 'ftrace/function-fork-v1' branch on

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
