The patch below fixes the checkpatch complaints on kfree():
WARNING: kfree(NULL) is safe this check is probabally not required
This patch has been verified as follows:
- Verified that checkpatch does no longer complain about kfree().
- Verified that make -s clean && make -s iscsi scst && make -s -C srpt
still works and does not trigger any new compiler warnings.
- Checked 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.
Note: I'm not sure any of the above verifications did trigger the code paths
changed by this patch.

The patch below fixes the following categories of checkpatch complaints:
- ERROR: switch and case should be at the same indent
- ERROR: do not initialise statics to 0 or NULL
- ERROR: use tabs not spaces
I have verified that the SCST source code still compiles.

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 fixes another category of checkpatch warnings, namely:
ERROR: "foo * bar" should be "foo *bar"
This patch has been verified by checking that the output of svn diff -x -w is

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

By this time I have reworked the update of scripts/generate-kernel-patch'>scripts/generate-kernel-patch.
These are the changes that were already present in version 1 of this patch
and that have been kept in this patch:
- The SCST code has been moved from drivers/scsi/scsi_tgt to drivers/scst.
- Moved SCST header files from include/scsi_tgt to include/scst.
- Added iscsi-scst in drivers/scst/iscsi-scst.
For the time being the generate-kernel-patch does no longer try to add the
qla2x00t driver in drivers/scst/qla2x00-target -- I have not yet been able to
figure out how to get qla2x00t/qla2x00-target compiled without the initiator
code.
Just as in version 1 of this patch, the following files in the Subversion
repository have been renamed to reflect the above changes:
- Renamed scst/kernel/in-tree/Makefile.scsi.Linux-2.6.24.patch'>scst/kernel/in-tree/Makefile.scsi.Linux-2.6.24.patch to
scst/kernel/in-tree/Makefile.drivers.Linux-2.6.24.patch'>scst/kernel/in-tree/Makefile.drivers.Linux-2.6.24.patch.
- Renamed Kconfig'>scst/kernel/in-tree/Kconfig.scsi.Linux-2.6.24.patch to
scst/kernel/in-tree/Kconfig.drivers.Linux-2.6.24.patch'>scst/kernel/in-tree/Kconfig.drivers.Linux-2.6.24.patch.
- Renamed scst/kernel/in-tree/Makefile.scsi_tgt'>scst/kernel/in-tree/Makefile.scsi_tgt to
scst/kernel/in-tree/Makefile.scst'>scst/kernel/in-tree/Makefile.scst.
- Renamed scst/kernel/in-tree/Kconfig.scsi_tgt'>scst/kernel/in-tree/Kconfig.scsi_tgt to
scst/kernel/in-tree/Kconfig.scst'>scst/kernel/in-tree/Kconfig.scst.
Because of the above changes the include path specified in the following
Makefiles had to be changed:
- scst/kernel/in-tree/Makefile.dev_handlers'>scst/kernel/in-tree/Makefile.dev_handlers
- srpt/src/Makefile.in_kernel'>srpt/src/Makefile.in_kernel
Other changes:
- I have added menu/endmenu entries in file scst/kernel/in-tree/Kconfig.scst
such that the SCST entries become visible when running make xconfig or make
menuconfig.
- Elaborated the SCST help texts a little bit (in file
scst/kernel/in-tree/Kconfig.scst).
New in version 2 of this patch:
- Moved remaining patches in the generate-kernel-patch script to separate
files.
- Added support for the 2.6.25 kernel.
This patch has been tested as follows:
mkdir -p tmp
cd tmp
rm -rf linux-2.6.25.3 /lib/modules/2.6.25.3-scst
tar xjf ~vanasscb/software/downloads/linux-2.6.25.3.tar.bz2

The script generate-kernel-patch generates a kernel tree based on the sources
and the in-tree kernel patches in the SCST Subversion repository. When I
submitted the first version of the generate-kernel-patch script most but not
all in-tree patches were present as separate files in the SCST Subversion
repository. The patch below moves the two remaining patches that are contained
inline in the generate-kernel-patch script to separate files. This should
make it possible to use the script on future Linux kernels without having to
modify the script itself. The patch below does not contain functional
changes, it only moves two patches out of the script.
Modified:
* scripts/generate-kernel-patch'>scripts/generate-kernel-patch
Added:
* srpt/src/Makefile.infiniband.Linux-2.6.24.patch'>srpt/src/Makefile.infiniband.Linux-2.6.24.patch
* srpt/src/Kconfig.infiniband.Linux-2.6.24.patch'>srpt/src/Kconfig.infiniband.Linux-2.6.24.patch
Also Makefile and Kconfig files were renamed (".drivers." was replaced by ".scsi.")

- Added Makefile.scsi.Linux-2.6.24.patch and Kconfig.scsi.Linux-2.6.24.patch
- Updated Makefile.scsi_tgt to reflect move of the SCST device handlers from scst/src/ to scst/src/dev_handlers/
- Added Makefile.dev_handlers
- SCST include path fixed in srpt/ Makefile.in_kernel
- Added script for converting the SCST source tree to a kernel patch. More comment on it:
The SCST source tree as it exists in the current Subversion repository will
have to be maintained for some time. And if SCST is submitted for inclusion
in the mainline kernel, this tree will have to be converted to a kernel
patch, reviewer comments will have to be processed, and the patch will have
to be resubmitted. So it's convenient to have a script available that
converts the Subversion source tree into a kernel patch. The patch below does
just that: convert the scst and srpt directories into a kernel patch
(iscsi-scst support will be added later on). I have tested the script
contained in the patch below as follows:
rm -rf linux-2.6.24
rm -rf /lib/modules/2.6.24-scst
tar xjf ~vanasscb/software/downloads/linux-2.6.24.tar.bz2
cd linux-2.6.24
cp ../.config .
(cd ~vanasscb/software/scst
&& ~vanasscb/software/scst/scripts/generate-kernel-patch \
2.6.24) | patch -p1
make -j5 bzImage modules && make modules_install install
cp -r /lib/firmware/$(uname -r) /lib/firmware/2.6.24-scst
update-initramfs -k 2.6.24-scst -c
reboot

- 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.
