Why setting cv->head to next of new node

[WweiL]

coursebook/appendix/appendix.tex

Line 846 in 1b53e6d

cv->head = my_node.next;

I was wondering the purpose of this line here. It seems that it is setting the head again to itself so essentially this line doesn't do anything. Should it be setting head to my_node?

Also I believe

coursebook/appendix/appendix.tex

Line 850 in 1b53e6d

while(my_node == 0) {

should be

while(my_node.is_awoken == 0) {

And probably the mutex dynamic inside

coursebook/appendix/appendix.tex

Lines 780 to 784 in 1b53e6d

	typedef struct cv_node_ {
	pthread_mutex_t *dynamic;
	int is_awoken;
	struct cv_node_ *next;
	} cv_node;

should rather be defined inside

coursebook/appendix/appendix.tex

Lines 786 to 788 in 1b53e6d

	typedef struct {
	cv_node_ *head
	} cond_t
