Merge tag 'nfsd-4.11' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields:
"The nfsd update this round is mainly a lot of miscellaneous cleanups
and bugfixes.
A couple changes could theoretically break working setups on upgrade.
I don't expect complaints in practice, but they seem worth calling out
just in case:
- NFS security labels are now off by default; a new security_label
export flag reenables it per export. But, having them on by default
is a disaster, as it generally only makes sense if all your clients
and servers have similar enough selinux policies. Thanks to Jason
Tibbitts for pointing this out.
- NFSv4/UDP support is off. It was never really supported, and the
spec explicitly forbids it. We only ever left it on out of
laziness; thanks to Jeff Layton for finally fixing that"
