What are you talking about? This is like complaining that we don't
have a single file containing all 16 years of history, some 400MB download
if someone wanted to see what the latest changes are. That commit message
was in changelog-stable.txt which you can still find online in the various
historical git repos and it's still present in the 3.14 changelog that
customers have access to now. You seem to be blaming your own laziness
on me -- it'd be like me complaining I have to use extra means to find
out who authored something prior to git history. And now you want to
use your laziness as a reason to try to claim that you don't know what
the authorship is of some code you copy and paste, so you choose to take
credit for it yourself:

Have you ever even contacted either of us when you were unsure or too
lazy to look it up? I know the answer to that question, and you know
the answer to that question, so quit with the BS.

Cryptomnesia I guess, you looked at every other line of PaX to rip out
stuff like:
https://github.com/thestinger/linux-hardened/commit/e63d5e4db605e74b2d9631219dd58301be484bd7
https://github.com/thestinger/linux-hardened/commit/93b646fed97b51e62cb48e0a25c2664cc2f86e0b
but totally never saw that line that's been there ever since SSP existed
in the kernel. It also doesn't mesh with your lengthy excuse on github
when I pointed it out to you. Are the above changes your own work too?

These false equivalences of yours are nonsense -- anyone can look at
https://github.com/thestinger/linux-hardened/issues
and see how utterly dependent you are. You are comparing apples and
oranges because you need to to justify your existence. You didn't
contribute a line of code to our work in 16 years and now you're trying
to make a name for yourself off our work and reputation. But you just
make a fool of yourself when on one hand you're desperately copy+pasting
and on the other trying to pretend you don't depend on it, or that your
dependence on copy+pasting our work is somehow equivalent to building on
top of whatever version of Linux that exists.
