Hi, v2-changelog ------------ Handle review remarks from Masahiro Yamada: - scripts/tags.sh: remove the O= language, and focus on the general case of the build directory being different from the kernel source tree, as specified in kernel Makefile L159. - Fix failure when build directory is a subdirectory of the kernel source tree. NEW: - Update Documentation/process/changes.rst with new gtags (GNU GLOBAL) requirements. Thanks! Cover letter / v1 ----------------- https://lkml.kernel.org/r/20230504201833.202494-1-darwi@linutronix.de make gtags for O= kernel builds is currently broken. For example, when doing: make O=../build/ x86_64_defconfig make O=../build/ gtags gtags generates a warning for each kernel source file to be indexed: make[1]: Entering directory '/home/darwi/build' GEN gtags Warning: '/home/darwi/linux/arch/x86/include/asm/qspinlock.h' is out of source tree. ignored. Warning: '/home/darwi/linux/arch/x86/include/asm/hpet.h' is out of source tree. ignored. ... Warning: '/home/darwi/linux/virt/lib/irqbypass.c' is out of source tree. ignored. make[1]: Leaving directory '/home/darwi/build/' and then generates an empty index: $ du -hs ~/build/G* 16K /home/darwi/build/GPATH 16K /home/darwi/build/GRTAGS 16K /home/darwi/build/GTAGS This series includes a proposed fix. After applying it: $ make O=../build/ gtags make[1]: Entering directory '/home/darwi/build' GEN gtags make[1]: Leaving directory '/home/darwi/build' $ du -hs ~/build/G* 9.1M /home/darwi/build/GPATH 506M /home/darwi/build/GRTAGS 696M /home/darwi/build/GTAGS The generated files can then be integrated with editors or IDEs as usual. => Ahmed S.
