From 24dc20c75f937b8f5c432e38275e70a1611766e9 Mon Sep 17 00:00:00 2001 From: Pavel Tatashin Date: Tue, 4 May 2021 18:39:15 -0700 Subject: mm/gup: change index type to long as it counts pages In __get_user_pages_locked() i counts number of pages which should be long, as long is used in all other places to contain number of pages, and 32-bit becomes increasingly small for handling page count proportional values.
