Hello,
This is v4 for libunwind callchain post processing speed up. It was able to reduce 50% of processing time by using global cache provided in libunwind. In this version, I decided to use the existing callchain_param.record_mode instead of adding a new field in the symbol_conf.
The patch 4 and 5 are just cleanups so that we can easily find out that which part of code uses the thread->priv.
You can also get it from 'perf/callchain-unwind-v4' branch on my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Thanks, Namhyung
