http://thread.gmane.org/gmane.linux.kernel.perf.user/882 is the most
recent patch I posted.
The last comments I got were:
* Use a global flag instead of a sort mode
* Try to integrate with LBR, branch filtering mode.
Unfortunately, I'm tied up with other projects right now and am not able
to finish this up. Happy to answer questions about the patch if anyone
wants to take it over.
http://thread.gmane.org/gmane.linux.kernel.perf.user/857 (callgraph
filtering) is also related.
