Tsirkin" <mst@...hat.com> Subject: [PATCH 1/3] kvm: use kmalloc() instead of kzalloc() during iodev register/unregister All fields of kvm_io_range were initialized or copied explicitly afterwards. So switch to use kmalloc(). Cc: Gleb Natapov <gleb@...nel.org> Cc: Paolo Bonzini <pbonzini@...hat.com> Cc: Michael S.
