Bug#661318: linux-image-3.2.0-1-amd64: Possibility integrating newer Hyper-V paravirt drivers in squeeze?

[Mathieu Simon <mathieu.sim@gmail.com>]

Package: linux-2.6
Version: 3.2.4-1
Severity: wishlist

Dear Maintainer,

Thank you for enabling the Hyper-V drivers in the 3.2 builds, the 
squeeze backport allowed me to test and confirm that they are not 
as broken as they once were. (in fact: far more stable than they used to be)

Unfortunately the 3.2 kernel only contains the paravirt bus (hv_vmbus)
utility (hv_utils) drivers out of staging. While mouse, networking 
block device drivers do work, it's only with Linux 3.3 that hv_mousevsc 
(later: hid-hyperv), hv_netvsc have left staging. 
linux-next also contains has hv_storvsc out of staging.

All 3 driver modules got a number of patches before they were accepted
to move out of staging. - Bug and feature fixes.

I for myself have tried and tested these drivers on a vanilla 3.2.x kernel 
with success. Ubuntu will also base their LTS releas on the 3.2 kernel 
- and they imported the changesets to their 3.2-based tree. 
(See: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/929545)

My question is: I'd really like to see a well working Kernel for wheezy on Hyper-V,
and therefore would like to elaborate the possibility to integrate the changes
from 3.3/linux-next into the wheezy kernel branch.

Although no big kernel hacking experience, I would be willing to prepare patches 
for wheezy if the kernel team would see that this backport would not hamper other
efforts in stabilizing wheezy.

Let me know if there is an interested and I'd be happy to prepare and test patches
on this platform.
