Subject: [PATCH v8 30/39] KVM: selftests: Export _vm_get_page_table_entry()
Date: Thu, 14 Jul 2022 15:49:20 +0200 [thread overview]
Message-ID: <20220714134929.1125828-31-vkuznets@redhat.com> (raw)
In-Reply-To: <20220714134929.1125828-1-vkuznets@redhat.com>
Make it possible for tests to mangle guest's page table entries in
addition to just getting them (available with vm_get_page_table_entry()).
