This thread is making me dizzy, but I think the patch you NAK'ed from me
was different.  It just added an error on GCC mismatch with external
modules:

  https://lkml.kernel.org/r/fff056a7c9e6050c2d60910f70b6d99602f3bec4.1611863075.git.jpoimboe@redhat.com

though I think you were ok with downgrading it to a warning.
