Subject: [PATCHSET 0/7] perf stat: Small random cleanups (v2)

Hello,

I'm working on perf stat and I found some items to clean up.  This time
I removed runtime stats for per-thread aggregation mode which we can simply
use thread map index to compare the shadow stat values in the rt_stat.

Changes from v1)
 * renaming missing parts in headers  (James)
 * add a comment for map_idx  (Ian)
 * add Reviewed-by from James

The code is available at 'perf/stat-cleanup-v2' branch in

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

Thanks,
Namhyung
