From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnaldo Carvalho de Melo Date: Fri, 23 Jan 2009 14:06:17 +0000 Subject: [PATCH tip][0/2] ftrace interface for blktrace Message-Id: <20090123140617.GB21737@ghostprotocols.net> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Jens Axboe Cc: Ingo Molnar , Steven Rostedt , Frederic Weisbecker , linux-kernel@vger.kernel.org, linux-btrace@vger.kernel.org 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.
