So? That chance is already there because the blacklist is already
there, but we cannot know until v3.12 is released, because that's when
most people would be testing that code.

It seems to me your worry is that somebody would report a regression
that happened v3.12-rc6 (if it has this patch applied), while it
worked correctly in v3.12-rc5, in which case you would get a complaint
from Linus.

But we all know that's not going to happen. The complaints (if any)
would arrive in v3.12, and that would happen regardless of this patch.

Besides, our goal is to make v3.12 as stable as possible, and it seems
to me you are blindly following the letter of a rule, instead if
interpreting what is the intent of rule. If I had sent the patch the
29th of June, it would have been aplied by now and be part of the
current blacklist, and the result would be the same; we cannot really
know until v3.12 is released.
