[PATCH 0/2] Fix multiple iscsi session unbind event sent to userspace

[Wenchao Hao]

kernel would send ISCSI_KEVENT_UNBIND_SESSION twice to userspace, for
open-iscsi, this would trigger iscsi_stop twice. We should fix this issue.

Here introduced a new session state ISCSI_SESSION_UNBOUND to address it.
Once session state is ISCSI_KEVENT_UNBIND_SESSION, it means
__iscsi_unbind_session() has been called for this session and do not need
to execute any more.

Reference:https://github.com/open-iscsi/open-iscsi/issues/338

Wenchao Hao (2):
  scsi: iscsi: introduce session UNBOUND state to avoid multiple unbind
    event
  iscsi: set session to FREE state after unbind session in remove
    session
