task_is_descendant(9) — from the Kernel API Manual, bestie ✨

Okay so this page is literally called task_is_descendant(9), and it lives in the Kernel API Manual. It's giving “family tree detective” energy, and we're gonna walk through it together 💅

int task_is_descendant (struct task_struct *parent , struct task_struct *child );
