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.
Name
