Re: [RFC, PATCH 3/3] knfsd: Modify write_ports to use svc_find_xprt service

[Tom Tucker <tom@opengridcomputing.com>]

Bruce:

What's the most efficient way for you to accept fixes/changes? I've been
going incremental because it's easy on me :-). Is this the best option for
you?

Regarding patch #6, I think the svc_find_xprt API _may_ be ok, but the
implementation was bogus (sorry). I _think_ the implementation is fixed in
the latest incremental. Greg can confirm.

WRT the suggestions below, I'll make those mods and test them tomorrow.

Thanks,
Tom
