Hi, In my driver (Process context), I have written the following code: -------------------------------------------- spin_lock(lock) ... //Critical section to manipulate driver data ... spin_u lock(lock) --------------------------------------------- I have written similar code in my interrupt handler (Interrupt context). The driver data is not accessed from anywhere else. Is my code safe from any potential concurrency issues? Is there a need to use spin_lock_irqsave()? In both the places? I intend to run the driver on SMP machine.
