Hi all, I have a query related to the usage of spin_lock_irqsave() and spin_lock() function calls. lets say I am in some critical section and I have two different locks, these locks are nested inside other, I can acquire these nested locks in two ways, I am not sure which one is more justified. The two possible way are as follows, please tell me the correct way? spin_lock_irqsave(&x_lock, x_lock_flags) ; . spin_lock_irqsave(&y_lock, y_lock_flags) ; <---- is this 'irqsave' justified? . . . spin_unlock_irqrestore(&y_lock, y_lock_flags) ; spin_unlock_irqrestore(x_lock, x_lock_flags) ; OR spin_lock_irqsave(&x_lock, x_lock_flags) ; . spin_lock(&y_lock) ; . . . spin_unlock(&y_lock) ; spin_unlock_irqrestore(x_lock, x_lock_flags) ; Which one is more correct or there are some other implications?
