"devices" directory at /sys/subsystem/<name>/devices.
If /sys/subsystem exists, /sys/bus, /sys/class and /sys/block can be
ignored. If it does not exist, you have always to scan all three
ignored. If it does not exist, you always have to scan all three
places, as the kernel is free to move a subsystem from one place to
the other, as long as the devices are still reachable by the same
subsystem name.
