commit: b94cfaf6685d691dc3fab023cf32f65e9b7be09c From: David Howells <[email protected]> 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.
