[RFC PATCH v2 14/41] nfsd: don't hand out uid 0 for read layouts of UUID-owned files

[sashiko-bot at kernel.org]

> Read-only flexfile layout segments use the owner's uid plus one, so the
> client gets no write access on the data server. For a UUID or GUID
> owner from_kuid() is -1 and the "plus one" makes it 0, root. Use the
> overflow uid for them instead.
