If a discovery address is removed from the /etc/iscsi.conf
file and a SIGHUP is sent to the daemon, what happens
to the exisitng sessions.
I don't think that the existing sessions with the targets
are cleaned up/terminated. The old sessions are left
The iscsi daemon should send the terminate IOCTL to
the driver and let the driver handle the pending IOs
on that session if any.
