    Description

      The main points in this patch are:

      • lowering the number of copy of the RIT list
      • lowering the number of synchronization
      • synchronizing on a region rather than on everything

      It also contains:

      • some fixes around the RIT notification: the list was sometimes modified without a corresponding 'notify'.
      • some tests flakiness correction, actually unrelated to this patch.
