Function tokio_util::sync::cancellation_token::tree_node::move_children_to_parent

fn move_children_to_parent(node: &mut Inner, parent: &mut Inner)

Moves all children from node to parent.

parent MUST have been a parent of the node when they both got locked, otherwise there is a potential for a deadlock as invariant #2 would be violated.

To acquire the locks for node and parent, use with_locked_node_and_parent.
