- 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 git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@366 d57e44dd-8a1f-0410-8b47-8ef2f437770f
