linux-next: build failure after merge of the kbuild tree

Hi all,

After merging the kbuild tree, today's linux-next build (arm64 perf) failed like this:

Presumably caused by commit

6a76b3c06a1d3 (kbuild: Reduce the number of compiler-generated suffixes for clang thin-lto build)

though I don't immediately see how. I have used the version from next-20260313 instead.

thanks for the report. Unfortunately, I cannot reproduce that anyhow; but I pushed to kbuild/kbuild-for-next at 12:36 UTC, might that have been a bad point in time? Do you have your merge somewhere around where I can fetch it for investigation?

Kind regards,
Nicolas

I tend to start late mornings UTC so something in the middle of the night won't be noticed. I don't have my merge to hand, sorry - you'll be able to see where I merged things by looking at the history of -next for the kbuild merge when I publish today's -next. IIRC there as nothing other than merges and the commit I flagged in there, it's possibly a merge issue with Linus' tree?
