From c164154f66f0c9b02673f07aa4f044f1d9c70274 Mon Sep 17 00:00:00 2001 From: Lorenzo Stoakes Date: Thu, 13 Oct 2016 01:20:13 +0100 Subject: mm: replace get_user_pages_unlocked() write/force parameters with gup_flags This removes the 'write' and 'force' use from get_user_pages_unlocked() and replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers as use of this flag can result in surprising behaviour (and hence bugs) within the mm subsystem.
