    workqueue: deprecate flush[_delayed]_work_sync() · 43829731
    Tejun Heo authored
    flush[_delayed]_work_sync() are now spurious.  Mark them deprecated
    and convert all users to flush[_delayed]_work().
    If you're cc'd and wondering what's going on: Now all workqueues are
    non-reentrant and the regular flushes guarantee that the work item is
    not pending or running on any CPU on return, so there's no reason to
    use the sync flushes at all and they're going away.
    This patch doesn't make any functional difference.
