Subject: [PATCH 204/246] migration: calculate expected_downtime
|
||
|
|
||
|
We removed the calculation in commit e4ed1541ac9413eac494a03532e34beaf8a7d1c5
|
||
|
|
||
|
Now we add it back. We need to create dirty_bytes_rate because we
|
||
|
can't include cpu-all.h from migration.c, and there is no other way to
|
||
|
include TARGET_PAGE_SIZE.
