From 74d81bfae8e3f52e956367f6ed764db269b87091 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Wed, 22 Feb 2017 15:44:41 -0800 Subject: mm: un-export wake_up_page functions These are no longer used outside mm/filemap.c, so un-export them and make them static where possible. These were exported specifically for NFS use in commit a4796e37c12e ("MM: export page_wakeup functions").
