| |
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
