Subject: [PATCH] pkt_sched: Annotate uninitialized var in sfq_enqueue()
Date: Fri, 19 Dec 2008 08:44:07 +0000 [thread overview]
Message-ID: <20081219084407.GC7189@ff.dom.local> (raw)
Some gcc versions warn that ret may be used uninitialized in
sfq_enqueue(). It's a false positive, so let's annotate this.
