workqueue: Set worker->desc to workqueue name by default
Work functions can use set_worker_desc() to improve the visibility of what the worker task is doing. Currently, the desc field is unset at the beginning of each execution and there is a separate field to track the field is set during the current execution. Instead of leaving empty till desc is set, worker->desc can be used to remember the last workqueue the worker worked on by default and users that use set_worker_desc() can override it to something more informative as necessary. This simplifies desc handling and helps tracking the last workqueue that the worker exected on to improve visibility. Signed-off-by: Tejun Heo <tj@kernel.org>
