Cant see where this is defined so this wont compile ? Please see arch/atomic.h for atomic arithmetic.
I have a question here:
Can I cast a uint32_t * to atomic_t * and then pass it to the atomic_add() function? Will it still be a atomic operation?
Why do you need to do this ? atomic_t can be used like a uint32_t within your code already.
OK, thats what I thought too but just wanted to confirm. Thanks!
