From: Oleg Nesterov on 30 Apr 2010 14:30 Export keventd_wq. Otherwise, any helper on top of queue_work() has to be copy-and-pasted to create the version which uses keventd_wq. Note: we can do more cleanups with this change and kill EXPORT_SYMBOLs, almost any function which currently uses keventd_wq can become the trivial inline.
