[PATCH v2 00/21] nfsd: more bugfixes

[Jeff Layton <jlayton@kernel.org>]

This version is addresses review comments from Sashiko. There wasn't
much in the way of regressions in v1, but it did notice a number of
nearby problems that should also be fixed.

This adds 3 patches to fix those. I also dropped the localio patch from
the series since that should probably go through the NFS client tree.
I'll send it separately.

AFAICT, these are garden-variety bugs. Chuck, please consider these for
v7.3.
