[GIT PULL] nfsd changes for 4.4

[GIT PULL] nfsd changes for 4.4

[J. Bruce Fields]

Please pull nfsd changes from

  git://linux-nfs.org/~bfields/linux.git tags/nfsd-4.4

Apologies for coming a little late in the merge window.  Fortunately
this is another fairly quiet one, mainly smaller bugfixes and cleanup.

We're still finding some bugs from the breakup of the big NFSv4 state
lock in 3.17--thanks especially to Andrew Elble and Jeff Layton for
tracking down some of the remaining races.
