Here's the outstanding items after going over everyone's comments
including Sashiko's:
+ KVM: TDX: Make source page optional for KVM_TDX_INIT_MEM_REGION
+ Need to move page clearing into __kvm_gmem_get_pfn to resolve
leak where populate can put initialized kernel memory into TDX
guest
+ See suggested fix at [1]
+ KVM: guest_memfd: Only prepare folios for private pages,
+ s/non-CoCo/CoCo in commit message "INIT_SHARED is about to be
supported for non-CoCo VMs in a later patch in this series
+ Use Suggested-by: Michael Roth <[email protected]>
+ KVM: selftests: Test that shared/private status is consistent across
processes
+ Improve test reliability using pthread_mutex
+ I have a fixup patch offline.
I would like feedback on these:
+ KVM: selftests: Test conversion with elevated page refcount
+ Askar pointed out that soon vmsplice may not pin pages. Should I
pin pages through CONFIG_GUP_TEST like in [2]? I prefer not to
take a dependency on CONFIG_GUP_TEST.
+ KVM: selftests: Add script to exercise private_mem_conversions_test
+ Would like to know what people think of a wrapper script before
I address Sashiko's comments.
