From a813a159766ee9d36aa1fc717c60d63325a6d077 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 9 Oct 2009 01:41:35 -0400 Subject: tracing: fix trace_vprintk call The addition of trace_array_{v}printk used the wrong function for trace_vprintk to call. This broke trace_marker and trace_vprintk itself. Although trace_printk may not have been affected by those that end up calling trace_vbprintk.
