Hello,
This is v3 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-v3' branch on my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Thanks,
Namhyung
