Option 3 would mean the behaviour can be different depending on the
kernel < 7.X having the backported patch or not tho, so we can't say
that with 100% certainty in the manpage, but it would need to also say
"this is true only if you don't have this specific bugfix patch, if your
kernel has it, then the behaviour is this other one".

(Sorry but I'll reply to the other points tomorrow, I'm too tired to
think about more difficult sentences right now :D)

Thanks.
