From d9b22d179a274013dd1eb29c7b9ab5225bfd7d70 Mon Sep 17 00:00:00 2001 From: Daniel Stodden Date: Mon, 25 Mar 2013 02:33:59 -0700 Subject: [PATCH] schedutils: don't apply -a without -p The unsuspecting user might use taskset -a mask command. Behavior then is to exec with no affinity applied at all. Better handled by ignoring all_tasks if no pid was given.
