what's the rationale behind the use of the odd-looking use of
calling WARN_ON_ONCE(1)? as in arch/i386/kernel/io_apic.c:
pin = find_isa_irq_pin(8, mp_INT);
if (pin == -1) {
WARN_ON_ONCE(1);
return;
}
based on my reading of that macro, wouldn't it be equivalent to just
write:
pin = find_isa_irq_pin(8, mp_INT);
if ((WARN_ON_ONCE(pin == -1)) {
return;
}
or am i misreading this? thanks.
