From: Steven Rostedt Date: Wed, 14 Jan 2009 19:50:19 +0000 (-0500) Subject: trace: stop all recording to ring buffer on ftrace_dump X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=0ee6b6cf5bdb793b4c68507dd65adf16341aa4ca;p=linux-2.6-omap-h63xx.git trace: stop all recording to ring buffer on ftrace_dump Impact: limit ftrace dump output Currently ftrace_dump only calls ftrace_kill that is a fast way to prevent the function tracer functions from being called (just sets a flag and clears the function to call, nothing else). It is better to also turn off any recording to the ring buffers as well.
