Use kvm_release_page_dirty() when unpinning guest pages, as the pfn was retrieved via pin_guest_page(), i.e. is guaranteed to be backed by struct page memory. This will allow dropping kvm_release_pfn_dirty() and friends. Signed-off-by: Sean Christopherson <seanjc@google.com> --- arch/s390/kvm/vsie.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
