The block layer is the same in qemu-kvm.git. The will be zero or very
few conflicts, so developing against qemu.git is the right thing. For
performance testing you may wish to git format-patch and apply those
patches to a qemu-kvm.git tree.
Please share what you plan to work on with the community. This can
save you a lot of time and avoid duplicating work. Before you post,
check out the "block layer roadmap thread" which lists many of the
proposed changes that have been discussed:

If you send an email explaining what you'd like to change you'll get
advice on how to get started.
