IMHO its useful even if we cannot swap it > out. Christoph, we need a way to swap these anonymous huge pages. You make it look as if you just want the anonymous huge pages and a way to then veto any attempts to make them swappable (on account of added overhead). I believe it will be more useful if we figure out a way forward together. Do you have any ideas on how to solve the hugepage swapping problem? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
