Build regressions/improvements in v5.16-rc7
From: Geert Uytterhoeven
Date: Mon Dec 27 2021 - 04:47:29 EST
Below is the list of build error/warning regressions/improvements in
v5.16-rc7[1] compared to v5.15[2].
Summarized:
- build errors: +7/-13
- build warnings: +39/-29
JFYI, when comparing v5.16-rc7[1] to v5.16-rc6[3], the summaries are:
- build errors: +2/-1
- build warnings: +23/-0
Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.
Happy fixing! ;-)
Thanks to the linux-next team for providing the build service.
