That is probably fine, I'm just arguing against the suggested changes
to syscall_get_error().

That said, I'm not sure why you want to change this in the first
place? I think the current syscall_get_error() - with explicit compat
handling and all - is fine.

But if the aim is to just remove syscall_get_error() entirely because
it's so unused, then I'm ok with that.
