we don't, somehow, inadvertantly overrun the total
number of queue entries for a command + continuation
segments.

recovery from not being able to push a ctio
fix is in. Various task management fixes are
also in. Other work in progress.

WARNING! This commit changes external SCST interface, so it can break compilation of your out of SCST SVN tree target driver or dev handler. To fix it, simply supply the preferred exection context to scst_cmd_done() and/or scst_tgt_cmd_done().
Thanks to Bart Van Assche <bart.vanassche@gmail.com> for pointing on it.

Add support for up through 2.6.25 (might even be good for 2.6.26)
Remove HBAAPI support. This never has worked well and I doubt anyone will miss it.
Remove files not pertinent SCST build.

The patch below fixes the following category of checkpatch warnings:
ERROR: Use of SPIN_LOCK_UNLOCKED is deprecated: see Documentation/spinlocks.txt
This patch has been verified as follows:
- Verified that checkpatch does no longer complain about spinlocks.
- Verified that make -s clean && make -s iscsi scst && make -s -C srpt
still works and does not trigger any new compiler warnings.
- Verified that the patch generated by generate-kernel-patch still applies
cleanly to the 2.6.25.4 kernel, and that the patched kernel tree still
compiles, installs and boots fine, and that the iscsi-scst, ib_srpt,
scst_disk and scst_vdisk modules still load.

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.

- Add comment about overall isp_scst.c design.
- Put some compile time selectable values in one place.

- "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
