You can use softirq instead. You can define your sofirq via editing include/linux/interrupt.h. and then use function rasie_softirq() instead of reuqest_irq(),which notify the kernel there is softirq needs to be processed. then kernel will execute it at a appropriate in software interrupt context.

Example API

1. open_softwareirq();
2. raise_softirq();
