From 4152ab377b55e9d3e5700de00ef799519ead698d Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 25 Jul 2011 11:06:19 -0300 Subject: [PATCH] perf evlist: Introduce 'disable' method To remove the last case of access to the FD() macro outside the library. Inspired by a patch by Borislav that moved the FD() macro to util.h, for namespace concerns I rather preferred to constrain it to ev{sel,list}.c.
