Hi Linus,

I'm not sure where git pull-request is getting the diffstat below, the
diff of the actual merge of this against mainline looks far less scary.
If I've botched something, please let me know.  Thanks,

Alex

  vfio: remove VFIO_GROUP_NOTIFY_SET_KVM (2022-05-24 08:41:18 -0600)

----------------------------------------------------------------
VFIO updates for v5.19-rc1

 - Improvements to mlx5 vfio-pci variant driver, including support
   for parallel migration per PF (Yishai Hadas)

 - Remove redundant iommu_present() check (Robin Murphy)

 - Ongoing refactoring to consolidate the VFIO driver facing API
   to use vfio_device (Jason Gunthorpe)

 - Use drvdata to store vfio_device among all vfio-pci and variant
   drivers (Jason Gunthorpe)

 - Remove redundant code now that IOMMU core manages group DMA
   ownership (Jason Gunthorpe)

 - Remove vfio_group from external API handling struct file ownership
   (Jason Gunthorpe)

 - Correct typo in uapi comments (Thomas Huth)

 - Fix coccicheck detected deadlock (Wan Jiabing)

 - Use rwsem to remove races and simplify code around container and
   kvm association to groups (Jason Gunthorpe)

 - Harden access to devices in low power states and use runtime PM to
   enable d3cold support for unused devices (Abhishek Sahu)

 - Fix dma_owner handling of fake IOMMU groups (Jason Gunthorpe)

 - Set driver_managed_dma on vfio-pci variant drivers (Jason Gunthorpe)

 - Pass KVM pointer directly rather than via notifier (Matthew Rosato)

It's all normal, and due to you having merges in your tree and
multiple merge bases.

See

    Documentation/maintainer/messy-diffstat.rst

for details (yay, Jonathan scrounged together docs so that I don't end
up having to write a long email explanation any more, and there are
links to some of my previous explanations on lore).

That also has a suggested remedy, ie just do a temporary merge and use
the diffstat from that one instead.

But I can also re-create that messy diffstat (and thus verify that
what you sent me matches what I got) here locally too.

So while the diffstat is messy and not very useful for a "this is what
changed" angle (because it has a lot of other changes mixed in), even
that messy diffstat is actually useful for my secondary reason, namely
as a verification that yes, I got what you were trying to send and
just didn't document very clearly because of those multiple merge
bases.

I can (and do) also check the shortlog, since the actual log doesn't
have any issues with merges, it's only "diff" that needs a single
well-defined <start,end> tuple.

Ok, so I should have gone the one step further than I did and replaced
the diffstat from pull-request with the one from my local test merge,
which would have looked like this:
