IOW, will all necessary attribute changes be reported as uevents ? Events needed are : - multipath topology changes : - path add/remove (well, this one is guarantied through /block I guess) - attributes changes - path state changes / path reinstates - path group switches - multipath add/remove (Deduce from /block uevents ?)
