[PATCH 00/40] Staging: hv: Driver 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.

[PATCH 0000/0117] Staging: hv: Driver cleanup
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
