For example I have not implemted a sysfs attr to read/write queue_if_no_path and a timeout attr so we do not have to wait forever on it.Comments???? Should I work with Christophe to convert the userspace tools?Nice, can libdevmapper event listening mecanisms be replaced by the uevents listener ? IOW, will all necessary attribute changes be reported as uevents ?
It looks like I am going to redo the patches and make it so dm call request_fns. So we are basicall going to fix up dm-multipath instead of making yet another multipath driver :)
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 ?)
I was just wondering where is all this netlink stuff? I have not seen a dm-netlink interface patch. Are you just keying of events from the kobject stuff?
