[Qemu-devel] [PATCH v2 0/7] backup improvements

[Vladimir Sementsov-Ogievskiy]

Hi all!

There are some fixes and refactorings I need on my way to resend
my backup-top series. It's obvious now that I need to share copying
code between backup and backup-top, as backup copying code becomes
smarter and more complicated. So the goal of the series is to make copying
code more share-able.

It's based on John's bitmaps branch, rebased on master.

v2 (by Max's comments):

02: Add Max's r-b
03: - split out backup changes to 03
    - handle common max_transfer = 0 case
04: splat out from 02
06: fix allocation size
07: - rebase on 06 changes
    - add Max's r-b

two patches are dropped or postponed for the next step

  block/io: handle alignment and max_transfer for copy_range
  block/backup: drop handling of max_transfer for copy_range
  block/backup: fix backup_cow_with_offload for last cluster
  block/backup: teach backup_cow_with_bounce_buffer to copy more at once
  block/backup: merge duplicated logic into backup_do_cow
