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!

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.
