I'm not a big fan of the verbose breakdown for every huge page size. As others have pointed out such detail exists elswhere.
But I do think we should have a summary counter for memory consumed by hugetlb that lets you know how much is missing from MemTotal. This can be large parts of overall memory, and right now /proc/meminfo will give the impression we are leaking those pages.
Maybe a simple summary counter for everything set aside by the hugetlb subsystem - default and non-default page sizes, whether they're used or only reserved etc.?
Hugetlb 12345 kB
