These files all use functions declared in interrupt.h, but currently rely on implicit inclusion of this file (via netns/xfrm.h). That won't work anymore when the flow cache is removed so include that header where needed. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
