nfsd bugfixes for 4.0

nfsd bugfixes for 4.0

[J. Bruce Fields]

Please pull nfsd bugfixes from

	git://linux-nfs.org/~bfields/linux.git for-4.0

Two main issues:

	- We found that turning on pNFS by default (when it's configured
	  at build time) was too aggressive, so we want to switch the
	  default before the 4.0 release.

	- Recent client changes to increase open parallelism uncovered a
	  serious bug lurking in the server's open code.

Also fix a krb5/selinux regression.

The rest is mainly smaller pNFS fixes.
