[RFC 0/2] migration: Tally pre-copy, downtime and post-copy bytes independently

[David Edmondson]

When examining a report of poor migration behaviour, it would often be
useful to understand how much data was transferred in different phases
of the migration process.

For example, if the downtime limit is exceeded, to know how much data
was transferred during the downtime.

RFC because the name "ram_transferred_add" doesn't seem great, and I'm
unsure whether the tests to determine the phase in the second patch
are the most appropriate.

David Edmondson (2):
  migration: Introduce ram_transferred_add()
  migration: Tally pre-copy, downtime and post-copy bytes independently
