Subject: [PATCH v3 3/5] bug: When !CONFIG_BUG, make WARN call no_printk to check format and args
Date: Sun, 9 Mar 2014 18:02:10 -0700 [thread overview]
Message-ID: <04b030fe345cba242bc672cecc79ee0cac1b79bd.1394412745.git.josh@joshtriplett.org> (raw)
In-Reply-To: <17c859aa7dcccec43df0a0c8908911b982764c76.1394412745.git.josh@joshtriplett.org>
The stub version of WARN for !CONFIG_BUG completely ignored its format
string and subsequent arguments; make it check them instead, using
no_printk.
