DESCRIPTION

22       The hugetlb memory memkind operations enable memory kinds which use the
23       Linux hugetlbfs file system.  For more information about the  hugetlbfs
24       see link below.

26
27       memkind_hugetlb_check_available_2mb()  Check  if  there  are  2MB pages
28       reserved  in  the  default   hugetlbfs.    If   the   kind   implements
29       ops.get_mbind_nodemask(),  then only the NUMA nodes set by the nodemask
30       are checked, otherwise every NUMA node is checked.
31
32       memkind_hugetlb_get_mmap_flags() Sets the flags for the  mmap()  system
33       call such that the hugetlbfs is utilized for allocations.
34
35       memkind_hugetlb_init_once()  This  function initializes MEMKIND_HUGETLB
36       kind  and  it  should  not   be   called   more   than   once.    Note:
37       memkind_hugetlb_init_once() may reserve some extra memory.
