Subject: [PATCH tip][0/2] ftrace interface for blktrace
Date: Fri, 23 Jan 2009 14:06:17 +0000 [thread overview]
Message-ID: <20090123140617.GB21737@ghostprotocols.net> (raw)
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
