Pull nfsd updates from Bruce Fields:
 "Various bugfixes, a RDMA update from Chuck Lever, and support for a
  new pnfs layout type from Christoph Hellwig.  The new layout type is a
  variant of the block layout which uses SCSI features to offer improved
  fencing and device identification.

  (Also: note this pull request also includes the client side of SCSI
  layout, with Trond's permission.)"
