--- Comment #5 from Torbjørn Birch Moltu <t.b.moltu at lyse.net> ---
My reasoning for choosing EACCES is that it's what unprivileged processes
already get, and Linux also returns this error. I agree that EINVAL is more
accurate though, and compatibility shouldn't matter in this case.
I'm a bit surprised that the approach in my patch is the proper solution.
Wouldn't it be better to check the type of node before opening or unlinking it?
