Hi Rajat, I think spin_lock_irqsave() will fulfill the purpose as otherwise it may be possible that the when a data structure is accessed in process context by taking spin_lock and an interrupt comes then the ISR will remain in forever loop waiting for the process context to release the lock result in a deadlock situation for a uniprocessor system.
HI Gaurav, I meant to use spin_lock_irqsave() in process context and spin_lock() in IRQ context.
