NAME

       memkind_hugetlb - hugetlb memory memkind operations.
       Note:  This  is  EXPERIMENTAL  API.  The  functionality  and the header file itself can be
       changed (including non-backward compatible changes) or removed.

SYNOPSIS

       int memkind_hugetlb_check_available_2mb(struct memkind *kind);
       int memkind_hugetlb_get_mmap_flags(struct memkind *kind, int *flags);
       void memkind_hugetlb_init_once(void);

DESCRIPTION

       The hugetlb memory memkind operations enable memory kinds which use  the  Linux  hugetlbfs
       file system.  For more information about the hugetlbfs see link below.
       ⟨https://www.kernel.org/doc/Documentation/vm/hugetlbpage.txt⟩

       memkind_hugetlb_check_available_2mb() check if there are 2MB pages reserved in the default
       hugetlbfs.  If the kind implements ops.get_mbind_nodemask(), then only the NUMA nodes  set
       by the nodemask are checked, otherwise every NUMA node is checked.

       memkind_hugetlb_get_mmap_flags()  sets  the flags for the mmap() system call such that the
       hugetlbfs is utilized for allocations.

       memkind_hugetlb_init_once() this function initializes MEMKIND_HUGETLB kind and  it  should
       not  be  called  more than once.  Note: memkind_hugetlb_init_once() may reserve some extra
       memory.
