Re: [PATCH v5 03/14] perf evsel: Move evsel__* functions to evsel.c

From: Ian Rogers <irogers@google.com>

At least one of these were put here to avoid a Python binding linking
issue which is no longer present. Put them back in their correct
location to avoid confusion about which file to add a new evsel__*
function to later.
