colleague just asked how he can use a single interrupt line to
trigger more than one interrupt handler, and i just said, "well,
IRQF_SHARED."
i'm not sure if there's any more to this problem, but am i off-base
in suggesting that that is pretty much what IRQF_SHARED is designed
for?
now, i do realize that it can be used along with a unique dev_id
values to isolate a *particular* handler amongst a group of handlers,
but if one simply wants to trigger *all* handlers registered for that
interrupt, is there anything about that that's tricky?
it seems pretty straightforward, but i'm going back to review my
interrupt handlers this evening.
