5cc78efff5 According to SPC-4 in the PERSISTENT RESERVE IN full status descriptor 
the format of byte 13 is defined as follows:
- The most significant four bits are SCOPE field.
- The least significant four bits are the TYPE field.
Make sure that that byte is filled in according to the specification.

f8c3b26620 disk_work.result is set by disk_cmd_done() and read by disk_exec(). 
Since there is a complete_all() / wait_for_completion() pair between both
accesses the volatile keyword is not necessary here.

59019ae405 Use get/put_unaligned() instead of open coding these such that the 
compiler can generate better code.

As an example, the get_unaligned_be24() function used in the
implementation of READ_6, WRITE_6 and VERIFY_6 together with
"& 0x1f0000" is inlined by the compiler and is translated as
follows on an x86_64 system (2031616 equals 0x1f0000):

        movl    0(%r13), %r11d
        bswapl  %r11d
        andl    $2031616, %r11d

Also eliminate a conditional branch instruction from get_trans_len_1_256().

33891c34fa In the function scst_mgmt_translate_lun() the variable tgt_dev is 
used as a loop variable and is used inside that loop only.
Hence it is not necessary to initialize it to NULL.

a2dcbab715 Fixes problem reported by Lev Vainblat <lev@zadarastorage.com>: 
The access to the session sysfs during logout may lead to the kernel oops. In iscsi_unreg_sess_done() the iscsi_session is freed, so scst_sess->tgt_priv (that previously pointed to the iscsi_session) becomes stale. The session is still accessible in sysfs until scst_sess_sysfs_del() call, but accessing to the session via sysfs may return invalid values or crash the kernel:

b3b4702bcb From Bart Van Assche <bvanassche@acm.org>: 
As Mikko Kortelainen <kordex@gmail.com> explained on the SCST IRC
channel, it's not necessary to replace the qla2xxx directory in the
kernel source tree in order to build the SCST qla2x00t target driver.
Also, if neither SCSI pass-through nor iSCSI will be used rebuilding
the kernel tree can be skipped entirely. The patch below updates the
qla2x00t howto accordingly, and also implements the following changes:
- Fix everything the W3C HTML validator complains about:
    - Add DOCTYPE declaration.
    - Add charset declaration.
    - Change </br> into <br> since </br> is invalid.
    - Change one occurrence of & into &amp;.
- Use proper HTML constructs for numbered and unnumbered enumerations.
- Use a fixed-sized font and the brown color for all computer output
text (via inline CSS).
- Use hyperlinks to refer to other steps.
- Fix spelling errors.
- Merge the Debian and non-Debian howto's because the differences are
so small that it's not justified to maintain two different documents.

cf04c8541a Implement building qla2xxx out of the kernel tree. For that 
BUILD_2X_MODULE=y should be passed to make. New module named
qla2xxx_scst. Obviously, to have it working, the original qla2xxx should
be either blacklisted, or removed from the target system.

This resulted in unnecessary complaints about IB completions not being
received in time when removing the ib_srpt kernel module during I/O. Note:
it is still possible that such complaints occur, but much less frequent.
