Hi all, After merging the tip tree, today's linux-next build (x86_64 allmodconfig) produced these warnings: WARNING: modpost: EXPORT symbol "device_match_devt" [vmlinux] version ... Is "device_match_devt" prototyped in ? I get thousands like this :-( I don't know what has done this, but there is a new Kbuild and modpost change: 2f35e67f621f ("kbuild: Fixup the IBT kbuild changes") -- Cheers, Stephen Rothwell
