v12: Treat target cluster size as BDRV_SECTOR_SIZE if bdrv_get_info failed or
doesn't set bdi.cluster_size;
v11: Rebase. The only difference is the "file" parameter of
bdrv_get_block_status_above.
Patch 1 rewrites mirror_iteration. Patch 2 is a small DRY cleaning up.
The main benefit is copying unallocated sectors (both zeroed and discarded)
doesn't go through the iov setup loop, as they don't need it.
Fam Zheng (2):
mirror: Rewrite mirror_iteration
mirror: Add mirror_wait_for_io
