Subject: linux-next: manual merge of the rcu tree with the rdma tree

Hi all,

FIXME: Add owner of second tree to To:
       Add author(s)/SOB of conflicting commits.

Today's linux-next merge of the rcu tree got a conflict in:

  drivers/infiniband/sw/rxe/rxe_mr.c

between commit:

  5bf944f24129 ("RDMA/rxe: Add error messages")

from the rdma tree and commit:

  330f72b82ab0 ("RDMA/rxe: Rename kfree_rcu() to kvfree_rcu_mightsleep()")

from the rcu tree.

I fixed it up (the code modified by the latter was moved by the former,
so I used this files from the former and applied the following merge fix
patch) and can carry the fix as necessary. This is now fixed as far as
linux-next is concerned, but any non trivial conflicts should be mentioned
to your upstream maintainer when your tree is submitted for merging.
You may also want to consider cooperating with the maintainer of the
conflicting tree to minimise any particularly complex conflicts.
