From 505c0efd58031923ae01deac16d896607cafa70e Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 23 Aug 2007 15:18:02 +0200 Subject: [PATCH] sched: tweak the sched_runtime_limit tunable Michael Gerdau reported reniced task CPU usage weirdnesses. Such symptoms can be caused by limit underruns so double the sched_runtime_limit.
