While I appreciate that it might be somewhat (a lot) harder for a filesystem to provide that guarantee, I'd be deeply worried about your claim that its impossible. It would render a system without swap very prone to deadlocks. Even with the very tight dirty page accounting we currently have you can fill all your memory with anonymous pages, at which point there's nothing free and you require writeout of dirty pages to succeed. -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
