Well, I assume that if some code defines a syscall, it will actually use it. Of course I meant to ask if the users of those definitions are going to just call sys_whatever. For example check_host_supports_tls in arch/um/os-Linux/sys-i386/tls.c which even uses the global errno (although in that case the whole else part could probably be just removed).
