As far as I understand it, no. Correct me if I'm wrong, but fast and slow
interrupts is about splitting interrupts into two kinds - serial io is
example of fast interrupt and network io is example of slow interrupt.

Sofirq in Linux is about splitting work done to serve one interrupt into two
parts - minimal and very fast interrupt handler schedules task done in
sofirq thread.
