From c1e7399da76646f34c3857147cca649cd58745af Mon Sep 17 00:00:00 2001 From: Bernd Schmidt Date: Sun, 21 Oct 2007 22:32:27 +0800 Subject: [PATCH] Blackfin arch: Fixing Bug: balance calls to get_task_mm with corresponding mmput calls We must balance calls to get_task_mm with corresponding mmput calls, otherwise refcounting is screwed up and mms don't get freed when their task exits.
