The server needs to be tested after these changes, and we need to make
sure the caches affected still work.
(I suspect the gid cache code will oops if it's used after these
patches, since the table is left NULl?)
And then we should also test in a container environment, with different
instances of mountd and rpc.svcidmapd running in each container, to
verify that the right thing happens.
