liballoc_lock
int liballoc_lock()
This function is supposed to lock the memory data structures. It could be as simple as disabling interrupts or acquiring a spinlock. It's up to you to decide.
return 0 if the lock was acquired successfully. Anything else is failure.
liballoc_unlock
int liballoc_unlock()
This function unlocks what was previously locked by the liballoc_lock function. If it disabled interrupts, it enables interrupts. If it had acquiried a spinlock, it releases the spinlock. etc.
return 0 if the lock was successfully released.
liballoc_alloc
void * liballoc_alloc(int pages)

The integer value is the number of pages to free.
return 0 if the memory was successfully freed.

calloc
void * calloc(size_t , size_t )
