[PATCH tip][0/2] ftrace interface for blktrace

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
