RE: Balloon pressuring page cache

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Isn't the hint only useful during the first round?

After the first round if a page becomes free then we need to update the copy at the migration destination, so freeing a page that previously had contents should mark it dirty.

 

 

Nope. I think as long as it is a free page (no matter 1st or 2nd round), we don’t need to send it.

 

Best,

Wei
