From: Steven Rostedt Date: Fri, 21 Nov 2008 17:59:38 +0000 (-0500) Subject: ftrace: add ftrace_off_permanent X-Git-Tag: v2.6.29-rc1~586^2~49^3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=69bb54ec05f57da7f6fac2cec0820cbc970df20f;p=pandora-kernel.git ftrace: add ftrace_off_permanent Impact: add new API to disable all of ftrace on anomalies It case of a serious anomaly being detected (like something caught by lockdep) it is a good idea to disable all tracing immediately, without grabing any locks. This patch adds ftrace_off_permanent that disables the tracers, function tracing and ring buffers without a way to enable them again. This should only be used when something serious has been detected. Signed-off-by: Steven Rostedt Signed-off-by: Ingo Molnar --- Reading git-diff-tree failed
