- PRIO queue was removed from scst_user. Instead, all priority commands now queued in the head of the regular queue. The corresponding code was removed from fileio_tgt as well. It necessary, in the future the priority queue can be easily restored from this patch.
- pre_unreg_sess() was removed from struct scst_dev_type. The corresponding code was removed from SCST core as well
- Almost all /proc/scsi_tgt commands now can fail after timeout (90 seconds) with EBUSY
- Fixed possible incorrect command's retry if double RESET UA is detected.
- Many minor changes and cleanups
Also docs were updated.

The patch below fixes the following class of checkpatch.pl errors:
ERROR("(foo*)" should be "(foo *)".
Or: another whitespace-only change.
I have verified that the output of svn diff -w -x is empty for this patch.

The patch below implements the following changes:
- Fixes the remaining warnings reported by checkpatch.pl with regard to the use
of whitespace in C code.
- Adds double qoutes around some #warning messages, such that checkpatch.pl
does no longer try to interprete the text behind the #warning preprocessor
directive.
- Adds an extra conversion to the generate-kernel-patch script that removes
the single space from before goto-labels while generating the kernel patch.
This patch has been tested as follows:
- Verified that svn diff -x -w only shows changes in the #warning preprocessor directives.
- Verified the output of svn diff by reading it.
- Verified that checkpatch.pl does no longer complain on the use of whitespace
(searched through the checkpatch.pl output for the text ' space').
- Verified that the patch generated by the generate-kernel-patch script still
applies cleanly to the 2.6.24 kernel, and that the patched kernel still compiles cleanly.
Please let me know if I have to resubmit parts of this patch to other SCST authors.

One of the Linux kernel patch submission requirements is that source files do
not contain trailing whitespace. The patch below removes trailing whitespace
from .c and .h source files.
Note: it might be more convenient to run the script I used to generate this
patch than to review and apply the patch below. This is how I generated and
verified the patch below:
cat <<EOF >./strip-trailing-whitespace
#!/bin/bash
trap "rm -f $t" EXIT
t=/tmp/temporary-file.$$
for f in "$@"
do
sed 's/[ ]*$//' <"$f" >"$t" && mv "$t" "$f"
done
EOF
chmod a+x ./strip-trailing-whitespace
find -name '*.[ch]' | xargs ./strip-trailing-whitespace
svn diff -x -w

- Minor external interface change: now target drivers should set for aborted commands SCST_CMD_DELIVERY_ABORTED status via scst_set_delivery_status(). In-tree drivers updated.
- Fixed broken compilation if put_page_callback patch not applied to the kernel. Reported by Erez Zilber <erezz@Voltaire.COM>
- Fixed several minor problems reported by David Berton <davidbrt@yahoo.com>
- Fixed __exit misuse, when such functions called from __init functions.
- Docs updated.
- Other minor changes and cleanups.

- "RECEIVE DIAGNOSTIC RESULTS" command handling fixed
- Obtaining device queue parameters in scst_obtain_device_parameters() changed to handle NOT READY sense
- Fixed possible dev_cmd_count underflow
- Minor iSCSI-SCST connection closing cleanups and fixes
- Semantic of other *_atomic flags changed a bit. Now they are intended only to allow SCST to optimize execution context. The corresponing functions now can *always* be called on atomic context and, if necessary, should manually determine that using scst_cmd_atomic() function and restart using corresponding *_NEED_THREAD_* return value.
- scst_cmd_get_tgt_resp_flags() and SCST_TSC_FLAG_STATUS flag made obsolete and replaced by scst_cmd_get_is_send_status(). All in-tree drivers updated accordingly
- Cleanup: preprocessing_done_atomic removed, now preprocessing_done() callback always called on thread context
- 64-bit cleanups
- Documented that iscsi-scst-adm is currently broken and explained why
- In user space Makefile's added possibility to specify external linker flags
- Minor performance optimizations
- Other minor cleanups

- TM fixes related to new commands serialization
- Other TM improvements
- Minor changes: likely/unlikely and priority of mgmt threads
Work not fully completed, still there are some rare issues.

- ABORT_CONSIDER_FINISHED_TASKS_AS_NOT_EXISTING compilation symbol added

Particularly:
- Added ability for target drivers to set result of command's status delvery to initiator (see scst_set_delivery_status())
- Added ability for user space devices set some mode page parameters to make SCST core behave correspondingly
- TM improvements
- Few possible crashes fixed
- Logging improvements
- Performance improvements
- Docs updates

Feature bits is set, indicating to the name server that this is an
initiator. The attached patch sets BIT_0 instead if target mode is
enabled, indicating target mode support to the name server. (See the
INCITS FC-GS-4 document). This fixed many of my problems relating to
working with a switch fabric, including the discovery and addition of
the initiator ports in the fcports list.
