In case if ELS LOGO command received on the target port,
the firmware can notify the driver about it in 3 different ways,
which handled differently by the driver (it doesn't clear when it use each way):
1. Immediate notify of login-affecting ELS command received (status code 0x46).
The target driver terminate all commands received for the specified initiator
(N_Port handle).
2. Asynchroneus event of port update.
The target driver only print message, and in remark it's written that
/* .mark_all_devices_lost() is handled by the initiator driver */
3. Immediate notify of port logged out (status code 0x29).
The target driver terminate all commands received for the specified initiator
(N_Port handle), and also mark all devices as lost.
In 1 and 2 everthing is OK. In 3 the target driver mark all devices as lost,
but never retrigger rescanning.
There are 2 solutions:
1. Not marking the devices as lost base on written in the async event case, and
also base on the spec which says to only terminate all commands.
2. Mark all devices as lost and retrigger rescanning.
1 was implemented; delete all calls to mark_all_devices_lost() in qla2x00t.c, and
unexport symbol of this function in qla_os.c

When double session is found in q2t_create_sess the session object is updated,
but after exiting from the function, if the session is not NULL the reference
counter is decrement, become zero and then the session is deleted.
As done while making a local session we need here to increment the reference
count by calling to q2t_sess_get, because at exiting we call to q2t_sess_put.

I had some problems compiling scst due to some bashisms in the Makefiles. As
you will know, Debian uses /bin/dash as default shell and /bin/sh is only a
link to /bin/dash. I can either change the default shell, (or in my opinion
the better solution) use SHELL=/bin/bash in the Makefile.
I have made a patch for the Makefiles in question (I hope, that are all
Makefiles).

is built via the kbuild infastructure. In kernel version 2.6.24 (commit
f77bf01425b11947eeb3b5b54685212c302741b8) the kbuild variable ccflags-y has
been introduced and the use of EXTRA_CFLAGS in kbuild makefiles has been
deprecated. The patch below converts SCST's in-tree makefiles such that these
use ccflags-y instead of EXTRA_CFLAGS when generating kernel patches for
kernel 2.6.24 or later.
Additionally, this patch removes the "default n" from the file
scst/kernel/in-tree/Kconfig.scst since this statement is superfluous.
The patch below has been tested by verifying the output of the following
command:
for ((v=23;v<=32;v++)); do rm -rf re* && scripts/run-regression-tests 2.6.$v; done
