Subject[PATCH 0/6] PCI: hv: VMbus requestor and related fixes
Date
Changes since RFC [1]:

- Rebase on hyperv-fixes (although more likely -next material)
- Fix handling of messages with transaction ID of 0
- Avoid reading trans_id from the ring buffer
- Move hv_pci_request_addr_match()&co. to VMbus
- Introduce primitives to lock and unlock the requestor
- Improve comments and log messages

The series got bigger (mainly due to a certain re-factoring in VMbus): the
hv_pci changes are in patches #2 and #6. Let me stress that the "PCI: hv"
patches and the "Drivers: hv: vmbus" patches below are inter-dependent.

Thanks,
