Failing to check for NULL\nmay lead to a NULL pointer dereference if the result is used later in\nprocessing, potentially causing crashes, data corruption, or undefined\nbehavior.\n\nOn XDP redirect failure, the associated page must be released explicitly\nif it was previously retained via get_page(). Failing to do so may result\nin a memory leak, as the pages reference count is not decremented.",
