From: Adrian Hunter Date: Wed, 4 Dec 2013 14:16:36 +0000 (+0200) Subject: perf script: Do not call perf_event__preprocess_sample() twice) X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a2cb3cf20e06ef119ae541c1a08dc1977f7f0fff;p=openwrt%2Fstaging%2Fblogic.git perf script: Do not call perf_event__preprocess_sample() twice) The perf_event__preprocess_sample() function is called in process_sample_event(). Instead of calling it again in perf_evsel__print_ip(), pass through the resultant addr_location.
