For the kvm_is_error_hva, ubsan complains if the uninitialized writable is passed to __direct_map, even though the value itself is not used (__direct_map goes to mmu_set_spte->set_spte->set_mmio_spte but never looks at that argument). Ensuring that __gfn_to_pfn_memslot initializes *writable is cheap and avoids this kind of issue. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
