From d01d4827858cdc2e1c437c87ab65ec0a00fd40f8 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 21 Sep 2009 11:06:27 +0200 Subject: sched: Always show Cpus_allowed field in /proc//status The Cpus_allowed fields in /proc//status is currently only shown in case of CONFIG_CPUSETS. However their contents are also useful for the !CONFIG_CPUSETS case. So change the current behaviour and always show these fields.
