i'm not the most intelligent linux user/person in general, so perhaps
i'm doing something stupid

i upgraded from nbd 2.9.15 to 2.9.16 and nbd-client -c doesn't return
the correct value when the device is disconnected,

m...@mybox:/opt/nbd-2.9.15$ sudo make install
blah blah blah
m...@mybox:/opt/nbd-2.9.15$ nbd-client -c /dev/nbd0
m...@mybox:/opt/nbd-2.9.15$ echo $?
1
m...@mybox:/opt/nbd-2.9.15$ sudo make uninstall
blah blah blah
m...@mybox:/opt/nbd-2.9.15$ cd ../nbd-2.9.16
m...@mybox:/opt/nbd-2.9.16$ sudo make install
blah blah blah
m...@mybox:/opt/nbd-2.9.16$ nbd-client -c /dev/nbd0
m...@mybox:/opt/nbd-2.9.16$ echo $?
0
m...@mybox:/opt/nbd-2.9.16$ sudo nbd-client mynbdserver 666 /dev/nbd0
Negotiation: ..size = 335544320KB
bs=1024, sz=335544320
m...@mybox:/opt/nbd-2.9.16$ nbd-client -c /dev/nbd0
2732
m...@mybox:/opt/nbd-2.9.16$ echo $?
0
m...@mybox:/opt/nbd-2.9.16$ sudo nbd-client -d /dev/nbd0
Disconnecting: que, disconnect, sock, done
m...@mybox:/opt/nbd-2.9.16$ nbd-client -c /dev/nbd0
m...@mybox:/opt/nbd-2.9.16$ echo $?
0



as you can see, nbd-2.9.15 returns the correct results, and nbd-2.9.16
always returns 0

is there an incompatability between the kernel module and the nbd code
i've downloaded?

modinfo nbd
