* pagevec_lookup_range - gang pagecache lookup
* @pvec: Where the resulting pages are placed
* @mapping: The address_space to search
* @start: The starting page index
* @end: The final page index
*
* pagevec_lookup_range() will search for & return a group of up to PAGEVEC_SIZE
* pages in the mapping starting from index @start and upto index @end
* (inclusive). The pages are placed in @pvec. pagevec_lookup() takes a
* reference against the pages in @pvec.
*
* The search returns a group of mapping-contiguous pages with ascending
* indexes. There may be holes in the indices due to not-present pages. We
* also update @start to index the next page for the traversal.
*
* pagevec_lookup_range() returns the number of pages which were found. If this
* number is smaller than PAGEVEC_SIZE, the end of specified range has been
* reached.
