Build regressions/improvements in v5.18-rc5
From: Geert Uytterhoeven
Date: Mon May 02 2022 - 03:02:48 EST
Below is the list of build error/warning regressions/improvements in
v5.18-rc5[1] compared to v5.17[2].
Summarized:
- build errors: +14/-6
- build warnings: +37/-21
JFYI, when comparing v5.18-rc5[1] to v5.18-rc4[3], the summaries are:
- build errors: +6/-21
- build warnings: +18/-5
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.
