/*
* FMD Dynamic Reconfiguration (DR) Event Handling
*
* Fault manager scheme plug-ins must track characteristics of individual
* pieces of hardware. As these components can be added or removed by a DR
* operation, we need to provide a means by which plug-ins can determine when
* they need to re-examine the current configuration. We provide a simple
* mechanism whereby this task can be implemented using lazy evaluation: a
* simple 64-bit generation counter is maintained and incremented on *any* DR.
* Schemes can store the generation number in scheme-specific data structures,
* and then revalidate their contents if the current generation number has
* changed since the resource information was cached. This method saves time,
* avoids the complexity of direct participation in DR, avoids the need for
* resource-specific processing of DR events, and is relatively easy to port
* to other systems that support dynamic reconfiguration.
