Mike Kravetz 7ca02d0ae5 hugetlbfs: accept subpool min_size mount option and setup accordingly ... Make 'min_size=<value>' be an option when mounting a hugetlbfs. This option takes the same value as the 'size' option. min_size can be specified without specifying size. If both are specified, min_size must be less that or equal to size else the mount will fail. If min_size is specified, then at mount time an attempt is made to reserve min_size pages. If the reservation fails, the mount fails. At umount time, the reserved pages are released.
