included in the generated patch output.
- Added command-line option -p <patchdir>, which allows to generate a
set of patches instead of one big patch.
- New feature: by setting the environment variable SIGNED_OFF_BY, the
Signed-off-by line is filled in.

- Add a dummy Signed-off-by line to the generated patch, such that checkpatch
doesn't complain that it's missing.
- Sort the names of source files (through ls) before using these, such that
the generated patch is the same during each run.
- Fixed a bug in #elif handling (this bug is not triggered by the current SCST
code).
This patch has been tested by comparing the output of the old and the new
generate-kernel-patch script.

- Converted tabs to spaces in the help text.
- Removed command-line option '-s' -- the srpt driver is now always included.
- Recognizes now both kernel versions with three components (x.y.z) and kernel
versions with four components (x.y.z.p).
- Empty files for Kconfig and Makefile are added for those components that are
not included in the kernel patch, such that make allyesconfig
/ make allmodconfig keeps working.

vanilla Linux kernel version. When I submitted this script for inclusion in the
SCST Subversion repository the SRPT target driver was excluded by default
because of checkpatch errors triggered by the SRPT source code. These errors
have been fixed considerable time ago. Hence the patch below makes inclusion
of the SRPT driver the default.
This patch has been tested by verifying that the generated patch still applies
cleanly to the 2.6.25.17 kernel, and that the patched kernel still compiles cleanly.

- The script specialize-patch now acts as if #define INSIDE_KERNEL_TREE 1
is effective.
- The script generate-kernel-patch now renames sBUG_ON() into BUG_ON()
and sBUG() into BUG(). The same script removes the definitions of the
sBUG_ON(), sBUG() and WARN_ON_ONCE() macro's from the header file
scst_debug.h. The last macro is only removed for kernel versions later than
2.6.19.
This patch has been tested as follows:
- Compared the output of the command "scripts/generate-kernel-patch 2.6.25"
before and after the changes.
- Verified the newly generated patch with checkpatch. Checkpatch statistics
are now as follows:
521 WARNING: line over 80 characters
12 WARNING: consider using strict_strtoul in preference to simple_strtoul
10 WARNING: printk() should include KERN_ facility level
3 WARNING: CVS style keyword markers, these will _not_ be updated
2 WARNING: do not add new typedefs
1 WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
- Verified that the generated kernel patch still applies cleanly to the
2.6.25.10 kernel and that this kernel still compiles, installs and boots fine.

The patch adds command-line options -m and -q to the script
generate-kernel-patch. These command line options make it possible to
choose at the time the script is invoked whether or not to include the
qla2x00t and/or mpt code in the generated kernel patch.

The patch below implements the following changes:
- Make sure the output of the make command does not appear in the generated
kernel patch.
- Changed interpreter of scripts/specialize-patch from /usr/bin/gawk to
/usr/bin/awk in order to make sure this awk script also runs on systems
where awk is installed but not gawk.
- Added an extra evaluation rule such that expressions like (0) are rewritten
as 0.
- Fixed a spelling error.
- Expressions that can only be partially evaluated are now partially evaluated.
E.g. #if defined(EXTRACHECKS) && (LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 18))
becomes #if defined(EXTRACHECKS) && 0 in the output.
- Code between #if 0 / #endif or #if 1 / #endif is included in the generated
kernel patch, including the surrounding preprocessor directives.
- Preprocessor statements with spaces behind # are now recognized (e.g. "# if").
- Expression evaluator now supports ! (logical not) and () (braces).
- #elif is now evaluated correctly.
- Nested #if / #elif / #else / #endif are now interpreted correctly.

The patch below contains a script that removes C preprocessor tests on the
LINUX_VERSION_CODE macro, depending on the kernel version that was passed as
an argument to that script. Furthermore, the generate-kernel-patch script has
been modified such that its output is filtered by the specialize-patch script.
This eliminates another class of checkpatch errors.
Note: due to the way the specialize-patch script is implemented, #if 0 and
#if 1 statements are also processed.
The patch below has been verified as follows:
- Checked that checkpatch does no longer complain about LINUX_VERSION_CODE
on the generated patch.
- Checked that the generated kernel patch applies cleanly to the 2.6.25.4
kernel.
- Checked that the patched kernel compiles and installs cleanly, and that
after reboot it was possible to load the iscsi-scst and ib_srpt kernel modules.
I will wait with sending more patches until this and the previous two patches
have been reviewed and/or applied.

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.

I don't know when this was broken, but with the current SVN version, after
having generated and applied a kernel patch for SCST, iscsi-scst doesn't
build anymore. The patch below fixes this and also includes a cleanup patch
for the generate-kernel-patch'>generate-kernel-patch script. The generated kernel patch has been
tested with the 2.6.24 and 2.6.25.4 kernels (extracted kernel sources +
applied patch + built kernel + installed kernel + reboot + load SCST
modules).

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

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
