[Stefan, myself] - Add HAVE_COPY_FILE_RANGE in configure. - Drop IDENT_DESCR_TGT_DESCR from scsi constants header. v7: Fix qcow2. v6: Pick up rev-by from Stefan and Eric. Tweak patch 2 commit message. v5: - Fix raw offset/bytes check for read. [Eric] - Fix qcow2_handle_l2meta. [Stefan] - Add coroutine_fn whereever appropriate. [Stefan] v4: - Fix raw offset and size. [Eric] - iscsi: Drop unnecessary return values and variables in favor of constants. [Stefan] - qcow2: Handle small backing case. [Stefan] - file-posix: Translate ENOSYS to ENOTSUP. [Stefan] - API documentation and commit message. [Stefan] - Add rev-by to patches 3, 5 - 10. [Stefan, Eric] This series introduces block layer API for copy offloading and makes use of it in qemu-img convert. For now we implemented the operation in local file protocol with copy_file_range(2). Besides that it's possible to add similar to iscsi, nfs and potentially more. As far as its usage goes, in addition to qemu-img convert, we can emulate offloading in scsi-disk (handle EXTENDED COPY command), and use the API in block jobs too.
