Date: Thu, 18 Jul 2013 16:31:18 +0800 From: "zhangwei(Jovi)" <jovi.zhangwei@...wei.com> To: Steven Rostedt <rostedt@...dmis.org> CC: Frederic Weisbecker <fweisbec@...il.com>, Ingo Molnar <mingo@...hat.com>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: [PATCH 2/3] tracing: add TRACE_ITER_PRINTK flag check in __trace_puts/__trace_bputs There missed TRACE_ITER_PRINTK check in __trace_puts/__trace_bputs, so add it, to constant with __trace_printk/__trace_bprintk, those functions mainly called by same function: trace_printk.
