Subject: [PATCH 02/26] dynamic_debug: make dynamic-debug supersede DEBUG ccflag
Date: Fri, 7 Oct 2011 14:33:08 -0600 [thread overview]
Message-ID: <1318019612-20068-3-git-send-email-jim.cromie@gmail.com> (raw)
In-Reply-To: <1318019612-20068-1-git-send-email-jim.cromie@gmail.com>
From: Jim Cromie <jim.cromie@gmail.com>
if CONFIG_DYNAMIC_DEBUG is defined, honor it over DEBUG, so that
pr_debug()s are controllable, instead of always-on. When DEBUG is
also defined, change _DPRINTK_FLAGS_DEFAULT to enable printing by
default.
Also adding _DPRINTK_FLAGS_INCL_MODNAME would be nice, but there are
numerous cases of pr_debug(NAME ": ...), which would result in double
printing of module-name. So defer this until things settle.
