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
Vladimir Sementsov-Ogievskiy (7):
block/backup: deal with zero detection
block/backup: refactor write_flags
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
