From aa22dd4990e38700b1855555aa0def5215859abb Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 16 May 2012 18:45:47 +0900 Subject: [PATCH] perf target: Rename functions to avoid double negation Rename perf_target__no_{cpu,task} to perf_target__has_{cpu,task} because it's more intuitive and easy to parse (for human beings) when used with negation. The names are came out from David Ahern. It is intended to be a mechanical substitution without any functional change. The perf_target__none remains unchanged since I couldn't find a right name and it is hardly used with negation.
