Subject: [KJ] [Patch] kmemdup() cleanup in drivers/media/video
Date: Mon, 23 Oct 2006 20:18:23 +0000 [thread overview]
Message-ID: <1161634704.419.9.camel@alice> (raw)
In-Reply-To: <1161634468.419.1.camel@alice>
hi,
replace open coded kmemdup() to save some screen space,
and allow inlining/not inlining to be triggered by gcc.
