Well, my worry is that 2M can be a high tax for smaller machines. Compile-time might be cleaner, but it has downsides. It is also not clear if these users actually need physical HZP or virtual is enough. Virtual is cheap.The kernel config flag (default =N) literally says don't use unless you have plenty of memory :) So this isn't an issue.
Distros use one-config-fits-all approach. Default N doesn't help anything. -- Kiryl Shutsemau / Kirill A. Shutemov
