Allow applications that program to the libhugetlbfs API to specify a page size
when requesting a hugetlbfs fd. If the size is invalid or not configured, an
error will be returned.
Changes since V1:
- Removed redundant handling when pagesize argument is zero

When multiple huge page sizes are available, libhugetlbfs behavior is to use
the huge page size reported in /proc/meminfo as the default size. Allow other
sizes to be used as the default via a new environment variable:
HUGETLB_DEFAULT_PAGE_SIZE. If this variable is specified, libhugetlbfs will
at
To avoid confusion, the library should store page sizes in bytes and library
interfaces should take page size parameters in bytes as well.
