Subject: perf record: Use evlist__new_default when no events specified
X-Git-Tag: v6.19-rc1~61^2~193
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3d3056a10504fab881bdba952b9b37bc09502c2c;p=thirdparty%2Fkernel%2Flinux.git

perf record: Use evlist__new_default when no events specified

Rather than distributing the code doing similar things to
evlist__new_default, use the one implementation so that paranoia and
wildcard scanning can be optimized.
