[Qemu-block] [PATCH 6/8] block/backup: teach backup_cow_with_bounce_buffer to copy more at once

backup_cow_with_offload can transfer more than on cluster. Let backup_cow_with_bounce_buffer behave similarly. It reduces number of IO and there are no needs to copy cluster by cluster. Signed-off-by: Vladimir Sementsov-Ogievskiy --- block/backup.c | 30 +++--- 1 file
