With the above said I'd suspect that we're safer leaving the include as is ? Yes, it is busted if one tries to use the standalone header, jet (most/all?) official users rely on that behaviour :-\ Cheers Emil -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
