From d72dc8a25afc71ce90ee92bdd77550e9beb85d4d Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 6 Sep 2017 16:21:18 -0700 Subject: mm: make pagevec_lookup() update index Make pagevec_lookup() (and underlying find_get_pages()) update index to the next page where iteration should continue. Most callers want this and also pagevec_lookup_tag() already does this.
