From 83b964bbf82eb13a8f31bb49ca420787fe01f7a6 Mon Sep 17 00:00:00 2001 From: Stephen Wilson Date: Sun, 13 Mar 2011 15:49:16 -0400 Subject: mm: arch: make in_gate_area take an mm_struct instead of a task_struct Morally, the question of whether an address lies in a gate vma should be asked with respect to an mm, not a particular task. Moreover, dropping the dependency on task_struct will help make existing and future operations on mm's more flexible and convenient.
