Subject: [PATCHSET 00/14] tools lib traceevent: Get rid of *die() calls from parse-filter.c (v2)

Hello,

This patchset tries to remove all die() calls in event filter parsing
code.  I changed two main functions of pevent_filter_add_filter_str()
and pevent_filter_match() to return a proper error code (pevent_errno).

The actual error message might be saved in a static buffer in pevent_
filter and it can be accessed by new pevent_filter_strerror() function.
The old pevent_strerror() still works for them too.

The only remaining bits are in trace-seq.c which implement print
functions and I want to hear what's the best way we can handle the
error case during the print.

I also put this patches on libtraceevent/die-removal-v2 branch in my tree

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


Any comments are welcome, thanks
Namhyung
