    workqueue: Set worker->desc to workqueue name by default · 8bf89593
    Tejun Heo authored
    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.
