SubjectBuild regressions/improvements in v5.18-rc1
Date
Below is the list of build error/warning regressions/improvements in
v5.18-rc1[1] compared to v5.17[2].

Summarized:
- build errors: +36/-15
- build warnings: +5/-38

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.

Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
