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

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



Namhyung Kim (4):
perf lock contention: Fix memory sanitizer issue
perf lock contention: Check --max-stack option
perf lock contention: Avoid variable length arrays
perf lock contention: Increase default stack skip to 4
