From d3f4b3855ba87caff8f35e738c7e7e3bad0a6ab1 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 25 May 2009 14:40:01 +0200 Subject: [PATCH] perf stat: flip around ':k' and ':u' flags This output: $ perf stat -e 0:1:k -e 0:1:u ./hello Performance counter stats for './hello': 140131 instructions (events) 1906968 instructions (events) Is quite confusing - as :k means "user instructions", :u means "kernel instructions". Flip them around - as the 'exclude' property is not intuitive in the flag naming.
