Hello Arun

Few hours ago was committed a patch in net-next-2.6, removing the need
for atomic_add_unless_return() in net/ipv4/inetpeer.c (so there no more
user in kernel at this moment for linux 3.1)


http://git.kernel.org/?p=linux/kernel/git/davem/net-next-2.6.git;a=commit;h=4b9d9be839fdb7dcd7ce7619a623fd9015a50cda
