Subject: Re: [PATCH] 2.3.99-pre6-3+ VM rebalancing
Date: Wed, 26 Apr 2000 05:45:08 -0700 [thread overview]
Message-ID: <200004261245.FAA03090@pizda.ninka.net> (raw)

If you start treating swap exactly the same, on a page-by-page LRU,
then a filesystem "find" scan will swap out most of your VM. Bad
news.
I never got the impression from the original posting that swap pages
would be treated "exactly" the same, and any sane LRU implementation
which included swap and anonymous pages would prefer clean page
liberation to dirty page liberation. I consider this a given.
Later,
