SubjectRe: [V9fs-developer] [PATCH 2/2] fs/9p: detecting invalid options as much as possible

The problem with that is that the same options are passed to the vfs,
net and transport init later on - none of which know the full subset of
valid options to tell what option has been recognized or not.

Unless we do some backward-incompatible breakage of passing all the
net/transport options in its own option (e.g. net=foo:bar:moo) there
unfortunately is no nice way of fixing this now.


(I don't mind the rest of the patches, although I'd say if we hit ENOMEM
there is likely trouble going on so I'm not so sure about hiding it if
there also is an EINVAL, but I don't really care)
