refcount_t

typedef struct refcount_struct refcount_t

typedef refcount_t - variant of atomic_t specialized for reference counts @refs: atomic_t counter field

The counter saturates at REFCOUNT_SATURATED and will not move once there. This avoids wrapping the counter and causing 'spurious' use-after-free bugs.
