    SubjectRe: [PATCH 50/50] kernel: Rename show_stack_loglvl() => show_stack()
    Hi Dmitry,

    Thank you for the patch! Yet something to improve:

    [auto build test ERROR on linus/master]
    [also build test ERROR on v5.4-rc6]
    [cannot apply to next-20191108]
    [if your patch is applied to the wrong git tree, please drop us a note to help
    improve the system. BTW, we also suggest to use '--base' option to specify the
    base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
