With the transition to workqueues, the implementation on the workqueue side is:

tasklet_enable() -> enable_work() + queue_work()

Ref: https://lore.kernel.org/all/20240227172852.2386358-7-tj@xxxxxxxxxx/

enable_and_queue_work() is a helper which combines the two calls.

Hope this answers your question.

Thanks,
