Eeek! Keeping a 'this is what we think userland thinks' state scares me. It
can and will get out of sync.
This is where the interface between PCMCIA socket drivers and the core code
got it right, IMO. You make the current state available, and occasionally
give hints like 'This bit may have changed. You might want to take a look."
Thinks.... a list of hotplug devices in a /proc file, listing some unique
per-instance ID against the type, topological information and current name
of the device. You don't send explicit add/remove events to userspace, just
an "Oi. Look again".
