It's also helpful to give attribution, not so much for the sake of giving credit, but to give other reviewers context. Something like: v3: Moved timer deadline to kvm_vmx_nested_state_hdr. [Paolo] v2: Fixed xyz. That helps reviewers understand what has changed and what feedback has been addressed (or to remind them of what feedback they gave :-D), and helps you avoid getting conflicting feedback. > Makarand Sonare (1): > KVM: selftests: VMX preemption timer migration test > > Peter Shier (1): > KVM: nVMX: Fix VMX preemption timer migration > > Documentation/virt/kvm/api.rst | 4 + > arch/x86/include/uapi/asm/kvm.h | 3 + > arch/x86/kvm/vmx/nested.c | 45 +++- > arch/x86/kvm/vmx/vmx.h | 2 + > arch/x86/kvm/x86.c | 3 +- > include/uapi/linux/kvm.h | 1 + > tools/arch/x86/include/uapi/asm/kvm.h | 1 + > tools/testing/selftests/kvm/.gitignore | 1 + > tools/testing/selftests/kvm/Makefile | 1 + > .../testing/selftests/kvm/include/kvm_util.h | 2 + > .../selftests/kvm/include/x86_64/processor.h | 11 +- > .../selftests/kvm/include/x86_64/vmx.h | 27 ++ > .../kvm/x86_64/vmx_preemption_timer_test.c | 255 ++++++++++++++++++ > 13 files changed, 344 insertions(+), 12 deletions(-) > create mode 100644 tools/testing/selftests/kvm/x86_64/vmx_preemption_timer_test.c > > -- > 2.26.2.761.g0e0b3e54be-goog >
