From 4377245aa93b65b6597e4b7bb460fb9abc48b56b Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 19 Feb 2009 13:41:27 -0500 Subject: [PATCH] ftrace: break out modify loop immediately on detection of error Impact: added precaution on failure detection Break out of the modifying loop as soon as a failure is detected. This is just an added precaution found by code review and was not found by any bug chasing.
