From a8ca5d0ecbdde5cc3d7accacbd69968b0c98764e Mon Sep 17 00:00:00 2001 From: Eric B Munson Date: Thu, 5 Nov 2015 18:51:33 -0800 Subject: mm: mlock: add new mlock system call With the refactored mlock code, introduce a new system call for mlock. The new call will allow the user to specify what lock states are being added. mlock2 is trivial at the moment, but a follow on patch will add a new mlock state making it useful.
