Can you comment on the aspect of configuring various kernel hugetlb 
configuration parameters? Especifically, what directory it should go in?
IMO it should be /sys/kernel/*

/sys/devices/system/etc should be fine eg. for showing how many pages are
available in a given node, or what kinds of TLBs the CPU has, but I would
have thought that configuring the kernel's hugetlb settings should be
in /sys/kernel.

Then again, I can't say I'm up to speed on sysfs policy so the main thing
I care about is that it is consistent and correct.

Thanks,
Nick
