This series fixes a potential segfault caused by NotifierList corruption
in xen-bus. The first two patches lay the groundwork and the third
actually fixes the problem.

Paul Durrant (3):
  xen / notify: introduce a new XenWatchList abstraction
  xen: introduce separate XenWatchList for XenDevice objects
  xen: perform XenDevice clean-up in XenBus watch handler
