120 be used to specify the offset into the underlying file. In such a case
136 hangs it off the VMA structure. In addition, the HPAGE_RESV_OWNER flag is set
167 modified to reflect the reservations. In the case of a shared mapping, a
189 consult the reservation map to determine if a reservation exists. In addition,
240 map based on the consumption of the reservation. In general, this involves
251 mapping. In such cases, the reservation count and subpool free page count
266 reverse mapping. In both cases, the PagePrivate flag is cleared. Therefore,
337 biggest reservation concern for COW is private mappings. In this case,
354 In the case where the faulting task is not the owner, the fault will fail and
359 non-owning task. In this way, the only reference is from the owning task.
360 In addition, the HPAGE_RESV_UNMAPPED bit is set in the reservation map pointer
406 the map. In most cases, the return value of region_add() is the same as the
409 region_chg() and region_add(). In this case, the return value of region_add()
420 map, all the individual file_region structures must be freed. In this case
422 - When a hugetlbfs file is being truncated. In this case, all allocated pages
423 after the new file size must be freed. In addition, any file_region entries
424 in the reservation map past the new end of file must be deleted. In this
426 - When a hole is being punched in a hugetlbfs file. In this case, huge pages
429 reservation map. In this case, region_del is passed the range
432 In every case, region_del() will return the number of pages removed from the
433 reservation map. In VERY rare cases, region_del() can fail. This can only
435 entry and can not allocate a new structure. In this error case, region_del()
443 region_count() is called when unmapping a private huge page mapping. In
458 page, so they just pass in an address instead of a range. In addition,
525 page is allocated but before it is instantiated. In this case, the page

541 attempting to restore the reservation map entry. In this case, it will
542 simply clear the PagePrivate flag of the page. In this way, the global
549 restore_reserve_on_error. In this case, it simply modifies the PagePrivate
