I assumed it would go through NFS tree, seeing that it's NFS-specific and
has nothing to do with any of the recent VFS changes (oops is triggerable
starting from 3.11); I can certainly put it through vfs.git, and there
will be changes nearby, but this one should go into -stable as a separate
patch.
