actually need it. This should improve performance on those versions of Linux
that do not need this.

there seems to be a problem with the Linux SCSI stack because when we delete a
LUN on the target, it does not get deleted from Linux. Still investigating.

TRACE_DBG("Created tid '%08lX'", (unsigned long)&tr_id[4]);
is wrong. All it will do is print the address of the fifth byte in the tr_id.
It should cast to an unsigned long * and deref it, at least. However, I have
anothe change that prints out the tr_id as a SAS address.

use an OUI that I think is not currently in use, so it seems unlikely that we
will clash with anyone else, but you never know. I might have to change it
later.

versions of Linux it was an unsigned char, and a value of 260 means 4 after a compiler warning. Added a comment to describe what is going on as well. Since
this is done very infequently it should not cause performance problems and
means that it will not silently fail to work if people try to use it on kernels
earlier than 2.6.26. If I figure out what kernel version the change was made
in we could use an ifdef.

- ISCSI preliminary completed commands handling fixes
- Write residuals cleanups and fixes
- Interface to handle residuals and received from initiators data changed
- BIDI cleanups and fixes.
- All BIDI IN fields and functions renamed to OUT to be in line with the in-kernel convention

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

- code indent should use tabs where possible.
- trailing whitespace.
- else should follow close brace '}'.

now report functions that are called with a lock held but that are missing
__acquires() and __releases() annotations. The patch below adds such
annotations and makes the following sparse warnings disappear:
drivers/scst/iscsi-scst/iscsi.c:2861:9: warning: context imbalance in 'iscsi_check_send_delayed_tm_resp' - unexpected unlock
drivers/scst/iscsi-scst/nthread.c:1614:17: warning: context imbalance in 'scst_do_job_wr' - unexpected unlock

The patch below has been tested by comparing the output of
"scripts/run-regression-tests 2.6.30.3" before and after the patch was applied.
