Merge tag 'nfsd-4.6-1' of git://linux-nfs.org/~bfields/linux

Pull more nfsd updates from Bruce Fields:
 "Apologies for the previous request, which omitted the top 8 commits
  from my for-next branch (including the SCSI layout commits).  Thanks
  to Trond for spotting my error!"

This actually includes the new layout types, so here's that part of
the pull message repeated:

 "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.

  Note this pull request also includes the client side of SCSI layout,
  with Trond's permission"
