 tag trace-3.11
 tagger Steven Rostedt <rostedt@rostedt.homelinux.com> 1373036548 -0400
 
 The majority of the changes here are cleanups for the large changes that
 were added to 3.10, which includes several bug fixes that have been
 marked for stable.
 
 As for new features, there were a few, but nothing to write to LWN about.
 These include:
 
 New function trigger called "dump" and "cpudump" that will cause
 ftrace to dump its buffer to the console when the function is called.
 The difference between "dump" and "cpudump" is that "dump" will dump
 the entire contents of the ftrace buffer, where as "cpudump" will only
 dump the contents of the ftrace buffer for the CPU that called the function.
 
 Another small enhancement is a new sysctl switch called "traceoff_on_warning"
 which, when enabled, will disable tracing if any WARN_ON() is triggered.
 This is useful if you want to debug what caused a warning and do not
 want to risk losing your trace data by the ring buffer overwriting the
 data before you can disable it. There's also a kernel command line
 option that will make this enabled at boot up called the same thing.
