This patch is being sent for use in the various Rust GPU drivers that are under development. It provides the additional feature of work items that are executed after a delay. The design of the existing workqueue is rather extensible, as most of the logic is reused for delayed work items even though a different work item type is required. The new logic consists of: * A new DelayedWork struct that wraps struct delayed_work. * A new impl_has_delayed_work! macro that provides adjusted versions of the container_of logic, that is suitable with delayed work items. * A `enqueue_delayed` method that can enqueue a delayed work item. This patch does *not* rely on the fact that `struct delayed_work` contains `struct work_struct` at offset zero. It will continue to work even if the layout is changed to hold the `work` field at a different offset. Please see the example introduced at the top of the file for example usage of delayed work items.
