"stray irqX" or "irqX: stray"

[Alexander Motin]

Hi.

Now we use different format for stray irq counters names (can be better
seen at `vmstat -ia`). Considering stray is a kind of special case (I
know no other cases using additional counters for interrupt source), I
still think it can be made somewhat more unified. I think we could
change "stray irqX" format to "irqX: stray". This format IMHO better
fits into existing naming scheme of "source: driver".

I propose such a patch:
--- intr_machdep.c.prev 2010-06-17 14:07:35.000000000 +0300

+++ intr_machdep.c      2010-06-23 09:18:52.000000000 +0300

@@ -334,8 +334,8 @@ intrcnt_register(struct intsrc *is)

        mtx_lock_spin(&intrcnt_lock);

        is->is_index = intrcnt_index;

        intrcnt_index += 2;

-       snprintf(straystr, MAXCOMLEN + 1, "stray irq%d",

-           is->is_pic->pic_vector(is));

+       snprintf(straystr, MAXCOMLEN + 1, "%s stray",

+           is->is_event->ie_name);

        intrcnt_updatename(is);

        is->is_count = &intrcnt[is->is_index];

        intrcnt_setname(straystr, is->is_index + 1);


Result looks like:
# vmstat -ia
