If a disk goes offline resulting in a force dismount, kfdp will message a B slave to do this. However, that may be queued behind other messages or there may be a flood of offline requests, all resulting in force dismounts.
There is no need to issue more than one force dismount though since force dismount should never fail. The processes will just be serialized, preventing the other B slaves from doing useful work.
