Hi, Kim,
>From the commit log of the commit b518154e59aa ("mm/vmscan: protect the
workingset on anonymous LRU"), you referred to the "used-once"
anon-pages. I have known about the use cases about used-once file cache
pages. But I don't know the use cases about the used-once anon-pages.
Can you teach me about that?
Or you doesn't mean used-once exactly, but accessing the pages for a
while after allocating the page, then never touch it again?
Best Regards,
Huang, Ying
