Linus Torvalds 5eb6eed7e0 One new feature was added to ftrace, which is the trace_marker now supports
triggers. For example:
 
   # cd /sys/kernel/debug/tracing
   # echo 'snapshot' > events/ftrace/print/trigger
   # echo 'cause snapshot' > trace_marker
 
 The rest of the changes are various clean ups and also one stable fix that
 was added late in the cycle.
