    SubjectRe: [PATCH v2 06/20] linux/kernel.h, linux/array_size.h: Split ARRAY_SIZE() into a separate header
    Hi Alejandro,

    Thank you for the patch! Perhaps something to improve:

    [auto build test WARNING on robh/for-next]
    [also build test WARNING on linux/master linus/master v5.16-rc2 next-20211118]
    [cannot apply to drm-intel/for-linux-next mkl-can-next/testing]
    [If your patch is applied to the wrong git tree, kindly drop us a note.
    And when submitting patch, we suggest to use '--base' as documented in
    https://git-scm.com/docs/git-format-patch]
