Can you explain how hugeadm --set-recommended-min_free_kbytes works and how it achieves this magic?  Or can you send me a pointer to how this works?   I've tried doing some Google searches, and I found the LWN article "Huge pages part 3: administration", but it doesn't go into a lot of detail how increasing vm.min_free_kbytes helps the anti fragmentation code.

Thanks,
