We have gfp_any() for this:
[EMAIL PROTECTED] net-2.6.24]$ grep gfp_any net/*/*.[ch]
net/ipv4/tcp.c: tcp_send_active_reset(sk, gfp_any());
net/ipv6/route.c: skb = nlmsg_new(rt6_nlmsg_size(), gfp_any());
net/ipv6/route.c: err = rtnl_notify(skb, pid, RTNLGRP_IPV6_ROUTE,
nlh, gfp_any());
net/netfilter/nfnetlink.c: netlink_broadcast(nfnl, skb, pid, group,
gfp_any());
net/netlink/af_netlink.c: skb = netlink_trim(skb, gfp_any());
[EMAIL PROTECTED] net-2.6.24]$ grep in_interrupt net/*/*.[ch]
net/decnet/dn_route.c: int user_mode = !in_interrupt();
net/decnet/dn_table.c: if (in_interrupt() && net_ratelimit()) {
