IMHO... I'd prefer it be off by default, for the obvious safety reasons. (It's under rapid development and particularly likely to have bugs). The only reason we had it on by default before was that we didn't add the switching mechanism early enough. (Well, and because we could keep it off in the config. But I'd rather be able to ship users a kernel that supports 4.1 and give them the option of turning it on at runtime, than make them build a new kernel.) --b.
