- * C11 does not hav an destruction function for atomic types, but some
- * implementations of the OVS atomics do need them. Thus, the following
- * function is provided for destroying non-static atomic objects (A is any
- * atomic type):
- *
- * void atomic_destroy(A *object);
- *
- * Destroys 'object'.

* ========
* ATOMIC_FLAG_INIT is an initializer for atomic_flag. The initial state is
* "clear".
*
- * C11 does not have an initialization or destruction function for atomic_flag,
- * because implementations should not need one (one may simply
- * atomic_flag_clear() an uninitialized atomic_flag), but some implementations
- * of the OVS atomics do need them. Thus, the following two functions are
- * provided for initializing and destroying non-static atomic_flags:
- *
- * void atomic_flag_init(volatile atomic_flag *object);
- *
- * Initializes 'object'. The initial state is "clear".
- *
- * void atomic_flag_destroy(volatile atomic_flag *object);
- *
- * Destroys 'object'.
+ * An atomic_flag may also be initialized at runtime with atomic_flag_clear().
