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. 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

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 vmbus driver: 1) Cleanup the interrupt handler by inlining some code. 2) Ensure message handling is performed on the same CPU that takes the vmbus interrupt. 3) Check for events before messages (from the host). 4) Disable auto eoi for the vmbus interrupt since Linux will eoi the interrupt anyway. 5) Some general cleanup. Regards, K. Y

More cleanup. In this patch-set we deal with the following issues: 1) While a Linux guest on Hyper-V can be assigned removable media devices (DVD, floppy etc), these devices are not handled by the Hyper-V block driver. So, we cleanup all the dead code dealing with removable media devices. 2) There were multiple functions to retrieve information about the device. Since much of

The latest upstream merge changed struct block_device_operations: This merge got rid of blkvsc_media_changed and introduced the function blkvsc_check_events. This broke all the patches that were sent after the tree was closed the last time. This is a resend of this patch-set to account for this change in the kernel. More cleanup.

Further cleanup of the hv drivers: 1) Cleanup the reference counting mess for both stor and net devices. 2) Handle all block devices using the storvsc driver. 3) Accomodate some host side scsi emulation bugs. 4) In case of scsi errors off-line the device. Regads, K. Y

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
