That's "use count", not "usecount". It's "count" as in "has meaning as a significator". 8-). I mean does msync() preterb the LRU order, by counting as a recent use? It's probably wrong to preterb the order, since what you are doing is forcing pages *out*. If you want them *out*, then they probably have lower locality than the pages you decided not to force out. In other words, msync() should probably not change the LRU order. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
