[PATCH 0/7] workqueue OwnedQueue, ScopedQueue and ScopedWork

[Danilo Krummrich <dakr@kernel.org>]

This series extends the Rust workqueue bindings with the ability to create
custom workqueues, enqueue non-'static work items on scoped queues, and
introduces ScopedWork, a work item type that cancels synchronously on drop,
allowing drivers to use workqueues with lifetime-bound data.

This picks up and extends prior work from Alice [1] and Onur [2]; changes I
subsequently applied, if any, are documented in the corresponding patch.

I also added a patch to replace the deprecated system_wq with
system_{percpu,dfl}_wq, which I originally sent with the WaitQueue series [3],
as it makes a bit more sense in this context.
