It would be helpful for reviewers to list the drivers here, since only
one is obvious from the patch.

Thanks for sorting the entry correctly!

Sorry, I will rewrite the subject.

Will add it.

Then, the commit log should be:


PCI: Add Alibaba Vendor ID to linux/pci_ids.h

The Alibaba Vendor ID (0x1ded) is now only used by Alibaba elasticRDMA
adapter driver. Move the Vendor ID to linux/pci_ids.h so that it can shared
by several drivers later.

Aha, you are welcome :)

Thank you for valuable comments.

Well, not exactly.  We don't want to merge changes that might be used
by unspecified drivers later.  We only want to merge things that are
needed *now*, i.e., when this complete series is merged.

In this case, I think it will be used by another driver that is part
of this series ("dwc_pcie_pmu"), so the commit log should mention both
Alibaba elasticRDMA ("erdma"?) and "dwc_pcie_pmu".

Yes, I have noticed the policy in head of include/linux/pci_ids.h.

	>  *	Do not add new entries to this file unless the definitions
	>  *	are shared between multiple drivers.

Actually, I mentioned both Alibaba elasticRDMA ("erdma") and PCIe PMU
"dwc_pcie_pmu" in initial draft. But I realized that dwc_pcie_pmu
is still in review, so I dropped it finally. :(

Anyway, I will add it back. Hope you are happy the bellow changes:

PCI: Add Alibaba Vendor ID to linux/pci_ids.h

The Alibaba Vendor ID (0x1ded) is now used by Alibaba elasticRDMA ("erdma") and
will be shared with the upcoming PCIe PMU ("dwc_pcie_pmu"). Move the Vendor ID
to linux/pci_ids.h so that it can shared by several drivers later.

Thank you.
