[NET]: Make netlink processing routines semi-synchronious (inspired by rtnl) v2
The code in netfilter/nfnetlink.c and in ./net/netlink/genetlink.c looks like outdated copy/paste from rtnetlink.c. Push them into sync with the original. Changes from v1: - deleted comment in nfnetlink_rcv_msg by request of Patrick McHardy Signed-off-by: Denis V. Lunev <den@openvz.org> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
