  * invalidate_mapping_pages - Invalidate all the unlocked pages of one
inode
- * @inode: the address_space which holds the pages to invalidate
- * @end: the index of the last page to invalidate (inclusive)

@nr_pages
+ * @mapping: the address_space which holds the pages to invalidate
+ * @start: the offset 'from' which to invalidate
+ * @end: the offset 'to' which to invalidate (inclusive)

  * This function only removes the unlocked pages, if you want to
  * remove all the pages of one inode, you must call
truncate_inode_pages.
  *
  * invalidate_mapping_pages() will not block on IO activity. It will
not
  * invalidate pages which are dirty, locked, under writeback or mapped
into
  * pagetables.
