In `child_circular_list()` address of local variable ���struct lock_struct a��� is assigned to `head.list.next` raising the following warning.
robust_list.c: In function ���child_circular_list���: robust_list.c:522:24: warning: storing the address of local variable ���a��� in ���head.list.next��� [-Wdangling-pointer=]
522 | head.list.next = &a.list; | ~~~~~~~~~~~~~~~^~~~~~~~~ robust_list.c:513:28: note: ���a��� declared here 513 | struct lock_struct a, b, c; | ^ robust_list.c:512:40: note: ���head��� declared here 512 | static struct robust_list_head head; | ^~~~
Defining the value with static keyword to fix this.
