With uname -a listing 4.4.0-100-generic #123-Ubuntu I get two change events, on the parent nbd3 device when connecting nbd export to /dev/nbd3 with two partitions (nbd3p1 and nbd3p2).
With uname -a listing 4.4.0-98 I do not get such events.
This bug is verified on xenial, will prepate matching systemd udev rules change SRU.
