Am I correct to assume that fs/nfs/nfsfilelayout* implements this API=
for the file layout case?


Tr= ue.
 
If so, I'll try an= d build glue that can use
that code unchanged (or at least minimally changed).

And Peter (I see you're on the cc list), is it possible to get a copy
of these files without any GPL? It looks like they have the U of Michigan copyright, which I think should be fine for the FreeBSD folks, but then
there is

  MODULE_LICENSE("GPL");

in it, which I assume means it's GPL'd. (Basically, exactly the same file,<= br> but released without this line, would make the FreeBSD folks happy, I think= .)
(No rush on this, I can use GPL'd code, I just can't put it in the FreeBSD<= br> source tree easily.) The same would apply to any other layout driver that others, like Panasas or EMC might be willing to open source for FreeBSD.

Not up to me, but it's more likely you'd = be able to get the Windows code
over the university license more = easily...

Benny
 

And Boaz, thanks for the useful information. I'll probably start with
Fedora plus a patched kernel for a server to test against. (It sounds
like Steve is willing to help me out, since I haven't used "rpm" = in
years and have never typed "git" in my life.:-)

Thanks everyone for your help with this, rick
