Pull misc fs warning fixes from David Howells:
 "The first four patches fix kerneldoc warnings in fscache, afs, 9p and
  nfs - they're mostly just comment changes, though there's one place in
  9p where a comment got detached from the function it was attached to
  (v9fs_fid_add) and has to switch places with a function that got
  inserted between (__add_fid).

  The patch on the end removes an unused symbol in fscache"
