* Return a user or a kernel stack in bpf program provided buffer.
* Note: the user stack will only be populated if the *task* is
* the current task; all other tasks will return -EOPNOTSUPP.
* To achieve this, the helper needs *task*, which is a valid
* pointer to **struct task_struct**. To store the stacktrace, the
* bpf program provides *buf* with a nonnegative *size*.
