Since I'll be travelling to Australia on tuesday morning, I'll not split this out into other things but will be porting the fair scheduler tomorrow ... that patch will also be available on my site. The patch is available at this URL: http://www.surriel.com/patches/2.4/2.4.0-tunevm+rss regards, Rik -- Virtual memory is like a game you can't win; However, without VM there's truly nothing to loose... http://www.surriel.com/ http://www.conectiva.com/ http://distro.conectiva.com.br/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
