Merge tag 'afs-fixes-20231221' of git://git./linux/kernel/git/dhowells/linux-fs

Pull AFS fixes from David Howells:
 "Improve the interaction of arbitrary lookups in the AFS dynamic root
  that hit DNS lookup failures [1] where kafs behaves differently from
  openafs and causes some applications to fail that aren't expecting
  that. Further, negative DNS results aren't getting removed and are
  causing failures to persist.

   - Always delete unused (particularly negative) dentries as soon as
     possible so that they don't prevent future lookups from retrying.

   - Fix the handling of new-style negative DNS lookups in ->lookup() to
     make them return ENOENT so that userspace doesn't get confused when
     stat succeeds but the following open on the looked up file then
     fails.

   - Fix key handling so that DNS lookup results are reclaimed almost as
     soon as they expire rather than sitting round either forever or for
     an additional 5 mins beyond a set expiry time returning
     EKEYEXPIRED. They persist for 1s as /bin/ls will do a second stat
     call if the first fails"
