SUPDrv,INTNet: Heads up! SupDrv version bumped. Added SUPR0ObjAddRefEx for dealing with the handle table callback which occurs while owning a spinlock. Normally SUPR0ObjAddRef[Ex] would always allocate a usage record, which means RTMemAlloc, but this is a bad idea when inside a spinlock. SUPR0ObjAddRefEx sports an additional parameter indicating whether it is allowed block or not.
