[GIT PULL] nfsd changes for 4.6

[J. Bruce Fields]

Please pull nfsd changes for 4.6 from

  git://linux-nfs.org/~bfields/linux.git tags/nfsd-4.6

----------------------------------------------------------------
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.)
