The current version negotiation code is not "future proof". Fix this by allowing each service the flexibility to either specify the highest version it can support or it can support the highest version number the host is offering. Signed-off-by:

The vmbus_prep_negotiate_resp() is only invoked when we are negotiating the version; so the current check in vmbus_prep_negotiate_resp() is unnecessary. Get rid of it. Signed-off-by:

After many years wandering the desert, it is finally time for the Microsoft HyperV code to move out of the staging directory. Or at least the core hyperv bus code, and the utility driver, the rest still have some review to get through by the various subsystem maintainers. Signed-off-by:

Now, properly handle util services in the util driver and eliminate code that will not be necessary. In the current code, util services were all handled not as other vmbus devices (net, block) but rather through special handling (channel setup etc.). In this patch we handle all services using the standard Linux Driver Model. Signed-off-by:

On some loaded windows hosts, we have discovered that the host may not respond to guest requests within the specified time (one second) as evidenced by the guest timing out. Fix this problem by increasing the timeout to 5 seconds. It may be useful to apply this patch to the 3.0 kernel as well. Signed-off-by:

The util module expects that the util channels are fully initialized when the module loads. To deal with the race condition which can result in a NULL pointer dereferencing if the util module were to load before all the util channels are fully initialized, in commit: commit: 8b5d6d3b Author: Haiyang Zhang <haiyangz@microsoft.com> Date: Fri May 28 23:22:44 2010 +000 code was introduced in the vmbus driver to ensure that all the util channels were fully initialized before returning from the load of the vmbus driver. This solution has several problems: if for whatever reason, any util channel were to fail to initialize, vmbus driver would wait indefinitely. We deal with this synchronization issue very differently in this patch. Signed-off-by:
