* Make sure that retreiving IET sessions actually work!
  + A session entry an be empty, where as a target entry
    can not. There for the session file is filled with
    _every_ target, but the cid/tid/etc values just isn't
    there...
    *blush* - to much cut-and-past! Need to reset all
    variables every time we get a new session entry.
* In iscsi_update_shareopts(), add the value we're called
  with at the end of the new (modified with 'name=...')
  shareopts variable.
* Use sizeof() instead of strlen() when copying values
  into the struct in iscsi_retrieve_targets_scst(). Don't
  want to risk overwriting the memory!
* s/EXTRA_SHARE_SCRIPT/EXTRA_ISCSI_SHARE_SCRIPT/g
* iscsi_target_s->iotype should be char[20], NOT [3]!
  + iscsi_target_s->iomode should be char[3]... Oups!
Make sure that the correct zfs_{share,unshare}_iscsi() is
called in the correct order in changelist_postfix().
+ We can't treat a iSCSI share the same way we would a
  NFS or SMB share... They are filesystems, iSCSI shares
  are ZVOLs!
