Can't you just register a delayed funtion in kfd_process_notifier_release() and call amd_iommu_unbind_pasid() from there? I really hate to make that part of the IOMMUv2 driver API, especially since it is going to be turned into a generic IOMMU-API extension.
And especially since all these hacks could be avoided if the KFD driver would just turn down everything on closing the file descriptor.
