Subject: linux-next: build failure after merge of the tip tree (net tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

net/sctp/bind_addr.c: In function 'sctp_bind_addr_clean':
net/sctp/bind_addr.c:148: error: 'sctp_local_addr_free' undeclared (first use in this function)

Caused by commit 1231f0baa547 ("net,rcu: convert call_rcu
(sctp_local_addr_free) to kfree_rcu()") interacting with commit
c182f90bc1f2 ("SCTP: fix race between sctp_bind_addr_free() and
sctp_bind_addr_conflict()") from the net tree.

I applied the following patch as a merge fix:
