-/**
- * pagevec_lookup_entries - gang pagecache lookup
- * @pvec: Where the resulting entries are placed
- * @mapping: The address_space to search
- * @start: The starting entry index
- * @nr_entries: The maximum number of pages
- * @indices: The cache indices corresponding to the entries in @pvec
- *
- * pagevec_lookup_entries() will search for and return a group of up
- * to @nr_pages pages and shadow entries in the mapping. All
- * entries are placed in @pvec. pagevec_lookup_entries() takes a
- * reference against actual pages in @pvec.
- *
- * The search returns a group of mapping-contiguous entries with
- * ascending indexes. There may be holes in the indices due to
- * not-present entries.
- *
- * Only one subpage of a Transparent Huge Page is returned in one call:
- * allowing truncate_inode_pages_range() to evict the whole THP without
- * cycling through a pagevec of extra references.
- *
- * pagevec_lookup_entries() returns the number of entries which were
- * found.
