Yeah I know, but I think that ship has already sailed as far as the naming we have in the kernel. We have over 250 uses of "exc", and several files called "exception" something. Using "interrupt" can also be confusing because Linux uses that to mean "external interrupt". But I dunno, maybe INT or VEC is clearer? .. or TRAP :) cheers
