The thing is.. the table is small-- how many pci devices are in the
system, anyways? and you -can't- do hotplug right without this kind of
functionality. e.g. you could use an exceptionall small linked list for
this purpose, e.g. <20 bytes per device.
Shouldn't that information be available in the device tree?
It also assumes that rescanning things after beginning to use them is
safe-- which might not necessarily be a safe assumption with broken
Huh? If you get a hotplug event, don't you need to reprobe the bus
to find out what the new devices are?
