Subject[PATCH 0/4] ftrace: Add 'function-fork' trace option (v2)
Date
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.

v2 changes)
* use ftrace_clear_pids() (Steve)
* add Ack from Masami

The code is also available at 'ftrace/function-fork-v2' branch on

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

Thanks,
Namhyung
