Peter Maydell 0d514fa234 Pull request ... * Copy offloading for qemu-img convert (iSCSI, raw, and qcow2) If the underlying storage supports copy offloading, qemu-img convert will use it instead of performing reads and writes. This avoids data transfers and thus frees up storage bandwidth for other purposes. SCSI EXTENDED COPY and Linux copy_file_range(2) are used to implement this optimization. * Drop spurious "WARNING: I\/O thread spun for 1000 iterations" warning -----BEGIN PGP SIGNATURE----- iQEcBAABAgAGBQJbFSBoAAoJEJykq7OBq3PISpEIAIcMao4/rzinAWXzS+ncK9LO 6FtRVpgutpHaWX2ayySaz5n2CdR3cNMrpCI7sjY2Kw0lrdkqxPgl5n0SWD+VCl4W 7+JLz/uF0iUV8X+99e7WGAjZbm9LSlxgn5AQKfrrwyPf0ZfzoYQ5nBMcQ6xjEeQP 48j2WqJqN9/u8RBD07o11yn0+CE5g56/f12xVjR5ASVodzsAmcZ2OQRMQbM01isU 1mBekJQkDxJkt5l13Rql8+t+vWz8/9BEW2c/eIDKvoayMqYJpdfKv4DqLloIuHnc 3RkquA0zUuKtl7xEnEkH/We7fi4QPGW/vyBN7ychS/zKzZFQrXmwqrAuFSw3dKU= =vZp+ -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/stefanha/tags/block-pull-request' into staging Pull request * Copy offloading for qemu-img convert (iSCSI, raw, and qcow2) If the underlying storage supports copy offloading, qemu-img convert will use it instead of performing reads and writes.
