I very much like the idea and I also think a "official" list of kernel security issues and 
respective fixes is very much required, since not every Linux distribution is supposed
to have kernel developers working for them, going through the whole changelogs 
looking for security issues, which is just silly.

Disclosing and bookkeeping of security issues is a job of the Linux kernel team.

Alan used to list down security fixes between each v2.2 release, v2.4 has never 
had such an official list (I'm trying to write CAN numbers on the changelogs lately), 
neither v2.6. Its not a practical thing for Linus/Andrew to do, its a lot of
work.

It would be interesting to have all developers to know about such initiative 
and have them send their security fixes to be logged and disclosed - its obviously
impossible for you to read all changes in the kernel. And have Linus/Andrew 
advocate in favour of it.

IMO such initiative needs to be known by all contributors for
it to be effective.

Yes, -ac has been playing that role. It is general consensus that 
such point releases are required. 

Linus doesnt do it because it is too much extra work him (and he is focused
on other things), glad you have stepped up.

You've been doing a lot of security work/auditing in the kernel for a long time, 
which fits the job position nicely.

I'm willing to help.
