[PATCH 0/4] perf lock contention: Small random fixes

[Namhyung Kim]

Hello,

This is a small update for the perf lock contention command.

The first issue is from msan (memory sanitizer) related to uninitialized
memory access and use of variable length array.

The other is to increase the default stack skip count to find appropriate
callers in most cases.

You can get it from 'perf/lock-con-fix-v1' branch in

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

Thanks,
Namhyung
