How to create Linux patches

• The old school way

• Before making your changes, make sure you have two kernel trees cp -a linux-2.6.37/ linux-2.6.37-patch/
• Make your changes in linux-2.6.37-patch/
• Run make distclean to keep only source files.
• Create a patch file: diff -Nur linux-2.6.37/ \ linux-2.6.37-patch/ > patchfile
• Not practical, does not scale to multiple patches

• The new school ways

• Use quilt (tool to manage a stack of patches)
• Use git (revision control system used by the Linux kernel developers)
