I still prefer solution 2, but for solution 1, you could do multiple things. You could leave them as them foo.o and foo-userspace.o. That is, build the kernel drivers without a rename. Whatever you do, you're going to hvae to be consistent.

Why would you do that? bar.c is part of the kernel driver, so it should be bar-kernel.o if you are renaming. You don't have to rename, of course. You could use 'foo.o' for kernel objects and 'foo-userspace.o' for userspace objects. Joel -- "People with narrow minds usually have broad tongues."
