[PATCH v5 0/2] hugetlb: display per-process/per-vma usage

[Naoya Horiguchi]

The previous version had build issues in some architectures, because it
required to move the definition of HUGE_MAX_HSTATE across header files
in order to embed a new data structure struct hugetlb_usage into struct
mm_struct. This was a hard problem to solve, so I took another approach
in this version, where I add just a pointer (struct hugetlb_usage *) to
struct mm_struct and dynamically allocate and link it.
This makes the changes larger, but no build issues.

Thanks,
Naoya Horiguchi
