Further cleanup of the hv drivers: 1) Continue to cleanup our drivers to conform to the Linux Driver Model. 2) Fix some long standing bugs with regards to unloading and reloading the drivers - block, net and stor. 3) VMBUS is an ACPI enumerated device; make VMBUS an ACPI bus driver. 4) Get rid of channel polling code; instead the channel receive paths will be purely interrupt

Further cleanup of the hv drivers. 1) Cleanup reference counting. 2) Handle all block devices using the storvsc driver. I have modified the implementation here based on Christoph's feedback on my earlier implementation. 3) Fix bugs. 4) Accomodate some host side scsi emulation bugs. 5) In case of scsi errors off-line the device. This patch-set further reduces the size of

Further cleanup of the hv drivers. Back in June I had sent two patch sets to address these issues. I have addressed the comments I got from the community on my earlier patches here: 1) Implement code for autoloading the vmbus drivers without using PCI or DMI signatures. I have implemented this based on Greg's feedback on my earlier implementation. 2) Cleanup error handling across

...I am not sure though if this is entirely relevant since we would be forking new processes in R instead of allowing a single process to use all cores. Apologies if this is utterly irrelevant.

This patch-set addresses some of the bus/driver model cleanup that Greg sugested over the last couple of days. In this patch-set we deal with the following issues: 1) Cleanup unnecessary state in struct hv_device and struct hv_driver to be compliant with the Linux Driver model. 2) Cleanup the vmbus_match() function to conform with the Linux Driver model. 3) Cleanup error

Greg, A few days ago you applied all the outstanding patches for the Hyper-V drivers. With these patches, I have addressed all of the known review comments for the vmbus driver (and a lot of comments/issues in other drivers as well). I am still hoping I can address whatever other issues/comments there might be with the intention to get the vmbus driver out of staging in the current window.
