v2->v3: - Fix the commit log in the second patch which causes "git am" to fail. - Remove the 1st patch in v2 as the problem will be fixed by another patch from Arnaldo.
v1->v2: - Include a compilation fix patch and a code streamlining patch into the patch set. - Use the __stringify() macro in stringify.h instead of adding a duplicate macro. - Add the --max-stack option to perf-top as well.
This perf patch set contains the following changes:
Patch 1 - Streamline the append_chain() function to make it run a bit faster. Patch 2 - Add a --max-stack option to perf-report to speed up its processing at the expense of less backtrace information available. Patch 3 - Add a similar --max-stack option to perf-top.
Waiman Long (3): perf: streamline append_chain() function perf-report: add --max-stack option to limit callchain stack scan perf-top: add --max-stack option to limit callchain stack scan
