I would prefer not to rename it. IRQ (Interrupt Request) is a signal
outside of the system. Below some frequency rate, amount of counted
ISR (interrupt service routine) calls or events would be equal to the actual
IRQs. If frequency is too high, we will count ISR, but not IRQs. In
any case, interrupt-counter is more or leas neutral, without triggering
too many wrong assumptions.

Regards,
Oleksij
