Dhugetlbfs_reserv.rst13 to be used. If no huge page exists at page fault time, the task is sent
36 This is a global (per-hstate) count of reserved huge pages. Reserved
39 as (``free_huge_pages - resv_huge_pages``).
40 Reserve Map
41 A reserve map is described by the structure::
52 There is one reserve map for each huge page mapping in the system.
67 These are stored in the bottom bits of the reservation map pointer.
82 Reservation Map Location (Private or Shared)
88 semantics of the reservation map is significantly different for the two types
91 - For private mappings, the reservation map hangs off the VMA structure.
