From 31db58b3ab432f72ea76be58b12e6ffaf627d5db Mon Sep 17 00:00:00 2001 From: Stephen Wilson Date: Sun, 13 Mar 2011 15:49:15 -0400 Subject: mm: arch: make get_gate_vma take an mm_struct instead of a task_struct Morally, the presence of a gate vma is more an attribute of a particular mm than a particular task. Moreover, dropping the dependency on task_struct will help make both existing and future operations on mm's more flexible and convenient.
