In addition, it should be a thread and not done from within keventd because : - It can take a long time (well, relatively but still too long for a work queue) - The driver callbacks might need to use keventd or do flush_workqueue to synchronize with their own workqueues when doing an internal recovery. > Since these are events rare, I've no particular concern about > performance or resource consumption.
