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:522:24: warning: storing the address of local variable ???a???
in ???head.list.next??? [-Wdangling-pointer=]
522 | head.list.next = &a.list;

Defining the value with static keyword to fix this.
