It should delete iommu_group_attach() and fix iommu_device_attach().
Yes. I am doing the functional and compile tests. I will post it once I complete the testing.
You also didn't really do my suggestion, this messes up the normal __iommu_attach_group()/__iommu_detach_group() instead of adding the clear to purpose iommu_replace_group() for VFIO to use. This just makes it more difficult to normalize the APIs.
I didn't forget that. :-) It's part of the new series.
Otherwise it does seem to have turned out to be more understandable. Jason
Best regards, baolu
