Hi,
thanks for the nice setup with scsi_debug that helps.
I also ran it against some real FCP devices I had around.
I can confirm that this still applies to Xenial.
1. working without issue on the device itself e.g. /dev/sd*
2. when using on /dev/mapper devices reporting issues
ubuntu@s1lp5:~$ sudo partprobe /dev/mapper/36005076306ffd6b6000000000000240
36005076306ffd6b60000000000002402

ubuntu@s1lp5:~$ sudo /sbin/sgdisk --new=2:0:100M --change-name=2:'ceph journal'

Creating new GPT entries.
Setting name!
partNum is 1
REALLY setting name!
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
The operation has completed successfully.

But then as you have shown as well, it is just a message about the ioctl that
likely isn't handled/forwarded correctly by the device mapper.
It doesn't even have a bad return code - so it might just be about
making more clear that this is a warning, but not an error at all right?
