Message-ID: <20060819171930.GJ7813@stusta.de>
Date: Sat, 19 Aug 2006 19:19:30 +0200
From: Adrian Bunk <bunk@...sta.de>
To: matthew@....cx, grundler@...isc-linux.org, kyle@...isc-linux.org
Cc: parisc-linux@...isc-linux.org, linux-kernel@...r.kernel.org
Subject: [2.6 patch] parisc: "extern inline" -> "static inline"
"extern inline" generates a warning with -Wmissing-prototypes and I'm
currently working on getting the kernel cleaned up for adding this to
the CFLAGS since it will help us to avoid a nasty class of runtime
errors.
If there are places that really need a forced inline, __always_inline
would be the correct solution.
