Greg Kroah-Hartman has posted a status update for drivers in the 2.6.32 kernel. This in particular, was rather funny:
hv (Microsoft Hyper-V) drivers. Over 200 patches make up the
massive cleanup effort needed to just get this code into a
semi-sane kernel coding style (someone owes me a bit bottle of
rum for that work!) Unfortunately the Microsoft developers
seem to have disappeared, and no one is answering my emails.
If they do not show back up to claim this driver soon, it will
be removed in the 2.6.33 release. So sad…
After all his work to get the patches in, Microsoft no longer gives a crap? Perhaps they did just do it because they were forced to after violating the GPL.
