At the very least we should get this done for a real filesystem to see how intrusive the changes are and to evaluate the performance changes. Sigh. A pox on whoever thought up huge pages. Words cannot express how much of a godawful mess they have made of Linux MM. And it hasn't ended yet :( My take is that we'd need to see some very attractive and convincing real-world performance numbers before even thinking of taking this on. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
