From cd3f2cd05cf1066f3975ed3223f12c799bc553c6 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Wed, 11 Sep 2013 14:25:53 -0700 Subject: [PATCH] pktcdvd: consolidate DPRINTK and VPRINTK macros Use the more common pkt_dbg(level, fmt, ...) form. These messages are emitted at KERN_NOTICE. Always emit function name with pkt_dbg(2, ...) uses and remove the sometimes abbreviated embedded function name. This form always verifies the format and arguments.
