The migration thread appears to want to allow writeout to occur at full
|
|
|
0a122b |
speed rather than being rate limited during completion of state saving,
|
|
|
0a122b |
but sets the limit to INT_MAX when xfer_limit is INT64_MAX. This causes
|
|
|
0a122b |
problems if there's more than 2GB of state left to save at this point. It
|
|
|
0a122b |
probably ought to just be INT64_MAX instead.
