Find oldest child (not sibling) of a process (task_struct)
From this post and this codebase, I know that there are pointers for
- Youngest child
- Youngest sibling
- Oldest sibling.
So with Oldest child, how do I get?
I am thinking of access "children" pointer (current->children) and traverse to the end of that doubly linked list.
