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"
