    For everyone else's benefit that's commit:

    c1c76700a0d6 ("Merge tag 'spdx-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx")

    Could you please include the commit title when citing a patch?

    ... did you try to bisect this?

    IIUC that's:

    WARN_ON_ONCE_GFP(order >= MAX_ORDER, gfp)

    ... and IIUC that's fixed by commit:

    11969d698f8cda31 ("cacheinfo: Use atomic allocation for percpu cache attributes")

    Thanks,
    Mark.
