This looks good to me now, much simpler. I will push this to -next soon,
but it won't be for v6.12. I have already sent PR for that. I want this
to be in -next for longer just to see if anyone has any comments and
doesn't break any platform(which it shouldn't anyways).

Just hoping if anyone looks at it and have feedback once it is in -next.
I will apply formally at v6.12-rc1 and report back if no one complains
until then.
