Re: [VM] 2.4.14/15-pre4 too "swap-happy"?

[Ken Brownfield]

Linus, so far 2.4.15-pre4 with your patch does not reproduce the kswapd
issue with Oracle, but I do need to perform more deterministic tests
before I can fully sign off on that.

BTW, didn't your patch go into -pre5?  Or is there an additional mod in
-pre6 that we should try?
