From 2d90508f638241a2e7422d884767398296ebe720 Mon Sep 17 00:00:00 2001 From: Nikanth Karthikesan Date: Thu, 13 Jan 2011 15:45:53 -0800 Subject: mm: smaps: export mlock information Currently there is no way to find whether a process has locked its pages in memory or not. And which of the memory regions are locked in memory. Add a new field "Locked" to export this information via the smaps file.
