But it forgets to do the same in backup_top_co_pwrite_zeroes, as well as declare support for BDRV_REQ_WRITE_UNCHANGED. Fix this, and, while being here, declare also support for flags supported by source child. Signed-off-by: Vladimir Sementsov-Ogievskiy <address@hidden> ---Reviewed-by: Eric Blake <address@hidden>
Thanks! -- Best regards, Vladimir
