[PATCH 4/6] dyndbg: increase verbosity for proc-show, proc-next

From: Jim Cromie
Date: Tue Sep 18 2012 - 19:37:44 EST


When dynamic_debug.verbose=1, catting /dbg/dynamic_debug/control
creates reams of log entries from ddebug_proc_(show|next|start|open).

Add vXpr_info() macro, and adjust verbosity required to enable those
callsites to 9 for show, next, and 8 for start, open. This leaves
other verbosity levels available should that appear useful later.
