Hi, Johannes
I'm a new comer to vm. And I read your commit 81c0a2bb about fair zone
allocator policy, but I don't quite understand your opinion, especially
the words that
"the allocator may keep kswapd running while kswapd reclaim
ensures that the page allocator can keep allocating from the first zone
in
the zonelist for extended periods of time. "
Could you or someone else explain me what does this mean in more
details? Or could you give me a example?
Thank you very much!!
