atomic_inc - increment atomic variable : pointer of type atomic_t
atomic_dec - decrement atomic variable : pointer of type atomic_t
Atomically increments by 1. Note that the guaranteed useful range of an atomic_t is only 24 bits.
Atomically decrements by 1. Note that the guaranteed useful range of an atomic_t is only 24 bits.
