Nice,

can libdevmapper event listening mecanisms be replaced by the uevents listener ?
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 ?)
