 * Why is there no list_empty_rcu()?  Because list_empty() serves this
 * purpose.  The list_empty() function fetches the RCU-protected pointer
 * and compares it to the address of the list head, but neither dereferences
 * this pointer itself nor provides this pointer to the caller.  Therefore,
 * it is not necessary to use rcu_dereference(), so that list_empty() can
 * be used anywhere you would want to use a list_empty_rcu().

 * However, if the list being initialized is visible to readers, you
