Maybe you're thinking of [3], which I do see in mainline where this was
2/2 in that series but afaict only patch 1/2 was committed. I guess
that explains why there was no respin based on comments for this patch.

If you take Alex's tree from here:
I navigated to this URL and clicked the green 'Code'
button. I was given the option to download the zip file or
use git to checkout the code at the URL displayed
''. I cloned the
repo at that URL and the code was definitely not in any
way similar to my code base. In particular, the
arch/s390/include/asm/kvm_host.h file did not have any
of the crypto structures.

I then downloaded the zip file and expanded it. The code
looked legitimate, but this was not a git repository, so I
had no way to cherry-pick my patches nor format patches
to post to this mailing list.

Next, I tried cloning from
but I was prompted for uid/pw.

So, the question is, how to I get the linux-vfio-next repo upon which I
can rebase my patches? I apologize for my ignorance.
You can use git fetch to download the objects, ex:

$ git fetch git:// next
$ git checkout FETCH_HEAD

Or you could add a remote, ex:

$ git remote add vfio git://
$ git remote update vfio
$ git checkout vfio/next

The former might be easier and add a lot less crufty objects to your
local tree if this is a one-off activity. Thanks,


Thanks Alex, I was able to get the repo, cherry-pick my patches and
build and test the kernel. Barring any anomalies, I will be posting the
patches today.
