struct llist_node* llist_del_first ( struct llist_head *  head )

read

llist_del_first - delete the first entry of lock-less list : the head for your lock-less list

If list is empty, return NULL, otherwise, return the first entry deleted, this is the newest added one.

Only one llist_del_first user can be used simultaneously with multiple llist_add users without lock. Because otherwise llist_del_first, llist_add, llist_add (or llist_del_all, llist_add, llist_add) sequence in another user may change ->first->next, but keep ->first. If multiple consumers are needed, please use llist_del_all or use lock between consumers.
