Subject: [PATCH 26/29] tools lib traceevent: Have bprintk output the same as the kernel does
Date: Mon,  4 Nov 2013 14:59:04 -0300	[thread overview]
Message-ID: <1383587947-17419-27-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1383587947-17419-1-git-send-email-acme@infradead.org>

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

The trace_bprintk() in the kernel looks like:

 ring_buffer_producer_thread: Missed:   0
 ring_buffer_producer_thread: Hit:      62174350
 ring_buffer_producer_thread: Entries per millisec: 6296
 ring_buffer_producer_thread: 158 ns per entry
 ring_buffer_producer_thread: Sleeping for 10 secs
 ring_buffer_producer_thread: Starting ring buffer hammer
 ring_buffer_producer_thread: End ring buffer hammer

But the current output looks like this:

 ring_buffer_producer_thread : Time:     9407018 (usecs)
 ring_buffer_producer_thread : Overruns: 43285485
 ring_buffer_producer_thread : Read:     4405365  (by events)
 ring_buffer_producer_thread : Entries:  0
 ring_buffer_producer_thread : Total:    47690850
 ring_buffer_producer_thread : Missed:   0
 ring_buffer_producer_thread : Hit:      47690850

Remove the space between the function and the colon.
