Yeah, but the case I'm worried about is plain anonymous. We already have the fs to back SHARED|ANONYMOUS, and they're not really anonymous. :) This patch *really* needs anonymous pages, and it kinda shoehorns them in with the filesystem. Stacks aren't shared at all, so this is a perfect example of where we can forget the fs, right? -- Dave ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Libhugetlbfs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libhugetlbfs-devel
