I don't really understand, how mountd's root can be wrong. I.e.

Or I'm missing something?
Ugh, I see the problem: I thought svc_export_request was called at the
time mountd does the read, but instead its done at the time nfsd does
the upcall.
I suspect that's wrong, and we really want this done in the context of
the mountd process when it does the read call. If d_path is called
there then we have no problem.
Right, so I'd be happier if we could modify sunrpc_cache_pipe_upcall to
skip calling cache_request and instead delay that until cache_read(). I
think that should be possible.
So, Bruce, what we going to do (or what you want me to do) with the rest of NFSd changes?
I.e. how I should solve this d_path() problem?
I.e. I don't understand what did you mean by "I'd be happier if we could modify sunrpc_cache_pipe_upcall to

Could you give me a hint?
