Hi all,
After merging the bitmap tree, today's linux-next build (htmldocs)
produced this warning:
Documentation/core-api/kernel-api:87: /home/sfr/next/next/include/linux/bitmap.h:425: WARNING: Unexpected indentation.
Documentation/core-api/kernel-api:87: /home/sfr/next/next/include/linux/bitmap.h:426: WARNING: Block quote ends without a blank line; unexpected unindent.
Documentation/core-api/kernel-api:87: /home/sfr/next/next/include/linux/bitmap.h:431: WARNING: Unexpected indentation.
Introduced by commit
6f46c24da767 ("bitmap: add bitmap_weight_{cmp, eq, gt, ge, lt, le} functions")

Hi Stephen,
(Adding Maxim Kuvyrkov from linaro/TCWG as he might be interested in
arm part of this.

I'll build docs and fix those warnings. Thanks for pointing this out.

I fixed tools build error and updated the bitmap-for-next branch. The
problem is that tools/perf
enables -Werror=sign-compare, and main kernel not. So direct copying
of functions from kernel
to tools doesn't work. This might be an issue by itself because I
think it would be better to keep
kernel and tools code consistent whenever possible.
Another problem is that the tools lacks testing from (obviously) me,
0-day and TCWG. I added
tools/perf to my testing build suite, and found that the build fails
for arm and s390 on v5.18-rc2.
See tools/perf build log attached.
Thanks,
Yury
