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
168 modified to reflect the reservations. In the case of a shared mapping, a
190 consult the reservation map to determine if a reservation exists. In addition,
241 map based on the consumption of the reservation. In general, this involves
252 mapping. In such cases, the reservation count and subpool free page count
267 reverse mapping. In both cases, the PagePrivate flag is cleared. Therefore,
338 biggest reservation concern for COW is private mappings. In this case,
355 In the case where the faulting task is not the owner, the fault will fail and
360 non-owning task. In this way, the only reference is from the owning task.
361 In addition, the HPAGE_RESV_UNMAPPED bit is set in the reservation map pointer
407 the map. In most cases, the return value of region_add() is the same as the
410 region_chg() and region_add(). In this case, the return value of region_add()
421 map, all the individual file_region structures must be freed. In this case
423 - When a hugetlbfs file is being truncated. In this case, all allocated pages
424 after the new file size must be freed. In addition, any file_region entries
425 in the reservation map past the new end of file must be deleted. In this
427 - When a hole is being punched in a hugetlbfs file. In this case, huge pages
430 reservation map. In this case, region_del is passed the range
433 In every case, region_del() will return the number of pages removed from the
434 reservation map. In VERY rare cases, region_del() can fail. This can only
436 entry and can not allocate a new structure. In this error case, region_del()
444 region_count() is called when unmapping a private huge page mapping. In
459 page, so they just pass in an address instead of a range. In addition,
526 page is allocated but before it is instantiated. In this case, the page

542 attempting to restore the reservation map entry. In this case, it will
543 simply clear the PagePrivate flag of the page. In this way, the global
550 restore_reserve_on_error. In this case, it simply modifies the PagePrivate
592 to check for regressions. In addition, if you add any new hugetlb
