From: Namhyung Kim Date: Wed, 18 Dec 2013 05:21:10 +0000 (+0900) Subject: perf sort: Do not compare dso again X-Git-Tag: firefly_0821_release~176^2~4647^2~4^2~47 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=68f6d0224b2a19a4da4a12a5081f01776e5150df;p=firefly-linux-kernel-4.4.55.git perf sort: Do not compare dso again The commit 09600e0f9ebb ("perf tools: Compare dso's also when comparing symbols") added a comparison of dso when comparing symbol. But if the sort key already has dso, it doesn't need to do it again since entries have a different dso already filtered out.
