Pull nfsd fixes from Bruce Fields:
 "Three nfsd bugfixes.

  None are new bugs, but they all take a little effort to hit, which
  might explain why they weren't found sooner"

* tag 'nfsd-4.20-1' of git://linux-nfs.org/~bfields/linux:
  SUNRPC: drop pointless static qualifier in xdr_get_next_encode_buffer()
  nfsd: COPY and CLONE operations require the saved filehandle to be set
  sunrpc: correct the computation for page_ptr when truncating
