Hi all!
These series introduce backup-top driver. It's a filter-node, which
do copy-before-write operation. Mirror uses filter-node for handling
guest writes, let's move to filter-node (from write-notifiers) for
backup too.
v11,v12 -> v13 changes:
[v12 was two fixes in separate: [PATCH v12 0/2] backup: copy_range fixes]
01: new in v12, in v13 change comment
02: in v12: add "Fixes: " to commit msg, in v13 add John's r-b
05: rebase on 01
07: rebase on 01. It still a clean movement, keep r-b

block/backup: fix max_transfer handling for copy_range
block/backup: fix backup_cow_with_offload for last cluster
block/backup: split shareable copying part from backup_do_cow
