From 53d8b3e798d7bb049a93a4ee97a2298241bda77f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 2 May 2010 20:55:06 +0200 Subject: [PATCH] sched: Warn on rt throttling commit 4b40e94233914642735b0a366cee9d0634224430 in tip. The default rt-throttling is a source of never ending questions. Warn once when we go into throttling so folks have that info in dmesg.
