In preparation for adding a function that walks a set of pages provided by userspace and populates them in a guest_memfd, add a version of kvm_gmem_get_pfn() that has a "bool prepare" argument and passes it down to kvm_gmem_get_folio(). Populating guest memory has to call repeatedly __kvm_gmem_get_pfn() on the same file, so make the new function take struct file*. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
