From 5aa60c6073456812251caf9177cb921b2de68f77 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Mon, 29 Sep 2008 23:02:37 -0400 Subject: ftrace: give time for wakeup test to run It is possible that the testing thread in the ftrace wakeup test does not run before we stop the trace. This will cause the trace to fail since nothing will be in the buffers. This patch adds a small wait in the wakeup test to allow for the woken task to run and be traced.
