Merge tag 'nfsd-5.7-rc-2' of git://git.linux-nfs.org/projects/cel/cel-2.6

Pull nfsd fixes from Chuck Lever:
 "Resolve a data integrity problem with NFSD that I inadvertently
  introduced last year.

  The change I made makes the NFS server's duplicate reply cache
  ineffective when krb5i or krb5p are in use, thus allowing the replay
  of non-idempotent NFS requests such as RENAME, SETATTR, or even
  WRITEs"
