Hi Jens,
Here is a third version, that also implements blk_add_trace_msg,
using ftrace_vprintk.
As soon as the TRACE_ITER_CONTEXT_INFO option is implemented
I'll provide the struct trace_event->bin() callback to synthesize the
old blktrace record format so that we can test the output of trace_pipe
with blkparse -i -.
Please let me know if this is acceptable for inclusion on
linux-tip.
Best Regards,
- Arnaldo

Cool - i've started tracking Arnaldo's patch by picking up the latest
version into tip/tracing/blktrace and merging it into tip/master.
Arnaldo, could you please check latest tip/master:
http://people.redhat.com/mingo/tip.git/README
to see whether it's all OK, integrated with the latest tracing bits?
Ingo
