Sigh, that didn't make much sense, did it? At the time, ia64 didn't support sharing IRQ vectors, and we preallocated four vectors for every slot, including empty ones. Allocate-on-demand dramatically increased the number of devices we could support because most cards use only one IRQ. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
