Subject: [PATCH] net: fix kmemcheck annotations
Date: Thu, 29 Oct 2009 11:10:37 +0100	[thread overview]
Message-ID: <4AE96A1D.8050300@gmail.com> (raw)

struct sk_buff kmemcheck annotations enlarged this structure by 8/16 bytes

Fix this by moving 'protocol' inside flags1 bitfield,
and queue_mapping inside flags2 bitfield.
