Subject: linux-next: manual merge of the cleancache tree with Linus' tree

Hi Dan,

Today's linux-next merge of the cleancache tree got a conflict in
fs/super.c between commit d863b50ab01333659314c2034890cb76d9fdc3c7 ("vfs:
call rcu_barrier after ->kill_sb()") from Linus' tree and commit
03e838947c8abe29a9d7abfaf7fd9125a46b70e9 ("mm/fs: add hooks to support
cleancache") from the cleancache tree.

I fixed it up (see below) and can carry the fix as necessary.
