The basic idea looks OK however:

* the function name (reset_hugepages) is a bit confusing
  what about "cap_hugepages" or "limit_hugepages"

* The MemFree: may be close to zero on long running system because of
  cached files, AFAIK MemAvailable: would be a better choice, see:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=34e431b0ae398fc54ea69ff85ec700722c9da773

  Unfortunately that one is available since 3.14 kernel, if we wanted to
  run on older kenrnels I would propose to fall back to dropping caches
  and using MemFree: on kernel that does not have MemAvailable: in
  meminfo.
