I don't avoid grsec because Linus says so. I avoid it because he says they break things when they don't need to. Security is a trade-off and I trust Linus in judging that and in ensuring the operating system should never break user space, unless it absolutely has to. If it does, I sure don't want to be stuck going to a group that goes against the spirit of the GPL (by punishing users who redistribute by cutting them off from future access) and which sues prominent members of the community essentially for pointing this out; which pretty much ensures I will be stuck going to them for support and not redistributing their work as I am permitted to under the GPL. No thanks to that kind of coercion!

I too am curious what the technical basis is for the patch but your assertion that drama is irrelevant is dangerous when applied to community projects that exist because of the goodwill of their members. grsec should be called out, when mentioned, because of their demonstrated ability to make the code they do produce less than useful because of the encumbrance it carries due to its origin.
