hi all,
I know that when an interrupt handler is excuting, the irq line which generated the signal will be masked out,however,if the line is shared by many device.Will all be masked out or just the one which is handling now be masked out ?Doed it tell the difference by the forth argument of request_irq() ?
------------------
best regards?

Hi,
shared/non-shared the corresponding interrupt line is masked out on
all processors.
preventing another interrupt on the same line from being received.
Thanks,
Rajath
