From: Lin Ming Date: Wed, 17 Aug 2011 10:42:07 +0000 (+0800) Subject: perf tools: Add group event scheduling option to perf record/stat X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=43bece79796c2a39ec98998fd3f1071f04f3d8c3;p=openwrt%2Fstaging%2Fblogic.git perf tools: Add group event scheduling option to perf record/stat Group event scheduling command line option is missing in perf record/stat. Add it to perf record/stat, which is same as in perf top.
