f36e96833d - scst_check_local_events() should be called in scst_real_exec() and 
scst_local_exec(), because if a command passed in those procedures, it
   for sure was delayed in some list, so recheck if it was aborted is
   necessary.

0c0cf3215b scstadmin: Multiple -write_config bug fixes. 
Bug fixes:
- Do not write out the line "# Non-key attributes" for the top level if -nonkey
  has not been specified.
- If -nonkey has been specified, write out the device handler creation time
  attributes too (blocksize, o_direct, read_only, removable, ...).
- If -nonkey has been specified, write out the LUN creation time attributes
  too (read_only).

Also, simplify the -write_config implementation by introducing the Perl
subroutines serializeKeyAttr() and serializeNkAttr().

daa5da87af Several wait loops in the SCST source code are similar. Move the common code 
into a new macro called wait_event_locked().

Signed-off-by: Bart Van Assche <bvanassche@acm.org>

+

Micro-optimize wait_event_locked(). Switch from default_wake_function() to
autoremove_wake_function() (via DEFINE_WAIT()). The result is that
wait_queue_head_t.lock is locked once instead of twice for wakeup + wait queue
removal.

ae269f6189 With NPIV initiators being destroyed and recreated, the loop_id and/or 
the d_id of a virtual initiator may change. The current implementation not
always catches these changes, which leads to wrong virtual devices
being presented to the initiators. This can lead to i.e. corruption of LUN
content and multiple initiators writing to the same LUN, although the
LUN's access group only contains a single port.

Until a better solution is found, we schedule a session deletion for the
nexus when receiving an ELS  port logout message. That way SCST
will re-initialize both loop_id and d_id when the initiator reconnects
before the actual deletion takes place. The performance impact is
minimal (few milliseconds) and currently necessary.
