Subject: linux-next: build failure after merge of the vfs-brauner tree

Hi all,

After merging the vfs-brauner tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ERROR: modpost: "fget_files_rcu" [arch/powerpc/platforms/cell/spufs/spufs.ko] undefined!

Caused by commit

  af66b51563ad ("file: convert to SLAB_TYPESAFE_BY_RCU")

I applied the following fix up patch.
