As discussed in the ML [1], there are some issues around the way ram.c accounts
for transferred data and dirty pages for the auto convergence calculations. The
patches in these series fix that by:
- Keeping bytes_xfer_prev zeroed until it's used
- Ensure bytes_xfer_* counters are accounted for the same period as
dirty_pages_* counters
- Start throttling in a consistent manner

Felipe Franciosi (4):
migration: keep bytes_xfer_prev init'd to zero
migration: set dirty_pages_rate before autoconverge logic
migration: set bytes_xfer_* outside of autoconverge logic
migration: use dirty_rate_high_cnt more aggressively
