Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers

Date:   Sun, 16 Sep 2001 15:00:17 -0700 (PDT)
From: Linus Torvalds 
Subject: Linux-2.4.10-pre10

Changelog appended..

Most of the patches are due to the continuing merge with Alan, others tend
to be fairly small.

However, I'd love for VM people to look at the page reference bit cleanups
- I might have missed some place that needs to mark something referenced,
but I also know I fixed a few places that hadn't done it right before.

For example, the old code did not react very well to read-ahead: it would
mark a page referenced on the first real access, if that page had earlier
been read in through read-ahead. In contrast, if it was _not_ read in with
read-ahead (ie the first page of a file, for example), it would not mark
the page referenced until the _second_ real access. Which just gives you
an idea of how truly random the aging used to be.

The new (simpler) code should be a lot less random. But it will probably
need a few tweaks. It would be very interesting to hear about specific
loads that show problems (or loads that are good, of course).
