Yup, I was referring to the two external projects. I also happen to think that only Xen matters because zcache is in staging. So that's one user in the tree.

You are changing core kernel code without ACKs from relevant maintainers. That's very unfortunate. Existing users certainly matter but that doesn't mean you get to merge code without maintainers even looking at it. Looking at your patches, there's no trace that anyone outside your own development team even looked at the patches. Why do you feel that it's OK to ask Linus to pull them? > P.S. before commenting further, I suggest that you read the > background material at http://lwn.net/Articles/454795/ > (with an open mind :-). I'm not for or against frontswap. I assume we need something like that since Xen and KVM folks are interested. That doesn't mean you get a free pass to add more complexity to the VM. So really, why don't you just use scripts/get_maintainer.pl and simply ask the relevant people for their ACK?
