My kernel version is 3.3.2, so you will have to adjust the directory names if you are using a different one. Everything up to the kernel building is distro-agnostic so this should help anyone at least get a patch going.I know you're not on fedora, but figured I'd put the whole thing up in case it helps someone. # Cloned bcache git: cd ~/ git clone git://evilpiepirate.org/~kent/linux-bcache.git # Added linux remote to the repository: cd linux-bcache git remote add linux git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git git fetch linux # Generate a patch of bcache changes to kernel. Note that this patch probably isn't directly # usable for kernel building, as there may be conflicts, so we have to go through the next step... git diff linux/master...bcache > ~/bcache.patch # Follow the standard fedora kernel build at http://fedoraproject.org/wiki/Building_a_custom_kernel # When you get to the section "Copy the Source Tree and Generate a Patch", go ahead and # create the tree as in that doc (but do yourself a favor and ignore the part about hard links, it's # much more trouble than it's worth, just copy) then apply your patch like so: cd ~/rpmbuild/BUILD/kernel-3.3.fc17.new/ patch -p1 < ~/bcache.patch # Look for merge conflicts! I missed one scrolling by and my kernel was inexplicably lacking # bcache support. Just to be sure, you could run this guy to find reject files generated by patch.. find ~/rpmbuild/BUILD/kernel-3.3.fc17.new/ -name "*.rej" # Fix any conflicts (they should be minor) and clean out any extra files generated by patch.. find ~/rpmbuild/BUILD/kernel-3.3.fc17.new/ -name "*.orig" | xargs rm find ~/rpmbuild/BUILD/kernel-3.3.fc17.new/ -name "*.rej" | xargs rm # Generate the patch as in the kernel doc. # The document then describes how to edit your SPEC file and build. Good luck! # One thing to note, I'd suggest starting with your existing config file (you can find it in # /boot/) instead of one of the templates when it comes time to configure. Make sure # you enable CONFIG_BCACHE when asked by `make oldconfig`! -Jason -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
