From b94cfaf6685d691dc3fab023cf32f65e9b7be09c Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 23 Feb 2012 13:51:00 +0000 Subject: NOMMU: Don't need to clear vm_mm when deleting a VMA Don't clear vm_mm in a deleted VMA as it's unnecessary and might conceivably break the filesystem or driver VMA close routine.
