From 2c3d103ba90827cfb478bf10464d9b5b9cea369c Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Fri, 25 Jul 2008 19:45:00 +0100 Subject: [PATCH] sched: move sched_clock before first use Move sched_clock() up to stop warning: weak declaration of `sched_clock' after first use results in unspecified behavior (if -fno-unit-at-a-time).
