Subject: Re: [PATCH net-next] netlink: Add nla_memdup() to wrap kmemdup()

Actually, is there any point in passing a GFP mask? None of the current
users need it, and it seems fairly unlikely to be needed since this is
typically used on the netlink input path, where you surely shouldn't
need GFP_ATOMIC or so?
