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

[Stephen Rothwell]

Hi Al,

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

arch/powerpc/platforms/cell/spufs/inode.c: In function 'spufs_show_options':
arch/powerpc/platforms/cell/spufs/inode.c:612:18: error: 'struct dentry' has no member named 'i_uid'
  if (!uid_eq(root->i_uid, GLOBAL_ROOT_UID))

Caused by commit

  4f9365d9e2e7 ("spufs: Implement show_options")

A bit hard to revert this, so I added the below patch for now ... please
fix it up.

Also, isn't this a bit late for this merge window?

Obvious incremental follows, will fold and push
