    Merge tag 'trace-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace · 5eb6eed7
    Linus Torvalds authored
    Pull tracing updates from Steven Rostedt:
     "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"
