Yes, I'd like to know how many huge pages are not available because of
the memory errors. Just like HardwareCorrupted in the /proc/meminfo.
But the HardwareCorrupted only adds one page size when a huge page is
hit by memory errors, and mixes with normal pages. So I think we should
add a new counts to track the memory errors on hugetlbfs.
