From 11bac80004499ea59f361ef2a5516c84b6eab675 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Fri, 24 Feb 2017 14:56:41 -0800 Subject: mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf ->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take a vma and vmf parameter when the vma already resides in vmf. Remove the vma parameter to simplify things.
