Subject: make -jN modules_install breakage in next-20230831
Date: Thu, 31 Aug 2023 16:59:22 +0800	[thread overview]
Message-ID: <CAGXv+5EU-qvTee1f0kicZA-er2Li=EcV0zWdOGUPoqdOxi69vw@mail.gmail.com> (raw)

Hi,

I observed some breakage with `make -jN moudles_install`. The scripts produce
some bogus paths, which `cp` then complains it can't find.

I run the following for my workflow.

  $ nice -n 10 sh -c "make -j72 Image.lzma dtbs && ./pack-mod.sh && cb/sign.sh"

pack-mod.sh is what fails. It basically does:

    make -j72 modules
    make -j72 modules_install INSTALL_MOD_PATH=${TMPDIR}
    depmod ...
    tar ...
    cleanup

I get errors like the following:

Note the duplicate "kernel/" in the path for test_udelay.ko and configs.ko.

If I revert commit 3ee3181f8721 ("Merge branch 'for-next' of
git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git"),
then everything works again. Not sure which commit is to blame though.
