Re: [PATCH] 9p: rename uid and gid parameters

[Latchesar Ionkov]

Zero was the value that was used before, even though it wasn't defined
explicitly. I just defined a macro so we can see and eventually change
it to something better. I don't know if there is a good default value.
Is nfsnobody the same on all Linux distributions?

Thanks,
