v2-changelog
------------

https://lkml.kernel.org/r/20230509012616.81579-1-darwi@linutronix.de

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!

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.
