Yeah, it's almost ready. At this point, I've addressed all the comments
except for:

- PATCH v2 25/40] tracing: Add support for dynamic tracepoints

which I need to do a little bit of research on to figure out what
exactly I need to do there.

I was also kind of looking for a couple patches from you to fold in
which you had mentioned you were going to send for:

- [PATCH v2 35/40] tracing: Reverse the order event_mutex/trace_types_lock are taken
- [PATCH v2 40/40] tracing: Add trace_event_buffer_reserve() variant that allows recursion

I've been using the trace_recursive_lock() patch you posted in place of
the latter and it's working fine. :-)
