The technical details of this pullreq are all fine (pgp key, format, etc), and it passes my build tests. But I gave this pullreq a bit of a closer inspection than I normally would, since it's your first, and there are a few things I thought worth bringing up: (1) I notice that some of the new files in this pullreq are licensed as "GPL, version 2", rather than "version 2 or any later version". Did you really mean that? Per 'LICENSE', we have a strong preference for 2-or-later for new code. (2) Some new files have no copyright or license comment at the top of them. Can you fix that, please? (3) Some of the new headers use kernel-internals __u32 etc types. This isn't portable. ('HACKING' has some suggestions for types you might want instead.) (4) One of your patches doesn't have any reviewed-by tags. We don't always manage to review everything, but it is nicer if we can get review, especially for patches from new submaintainers. (5) This is an absolutely enormous diffstat for a single commit: 26 files changed, 5149 insertions(+), 4 deletions(-) thanks -- PMM

If we're using kernel header files, I would recommend using the scripts/update-headers machinery for this, the way we do for other kernel headers. Among other things, the cp_portable function in that script will fix up the type names for you. thanks -- PMM

I don't think this is done like this anywhere in code. Please take a look at how it's done for e.g. input.h I think that whenever a rule in HACKING, coding style, etc is ignored it should be accompanied by motivation in code comments, so this won't spread out any more. -- MST

I spent some time to review this but got lost when it became too specific (this is not really my area). I was hoping some of the VMware folks could review this. KVM related stuffs are hard to test, but we have some qtests (migration mostly). Adding some tests for this huge code addition would be really great. Regards, Phil.
