From 6c5d523826dc639df709ed0f88c5d2ce25379652 Mon Sep 17 00:00:00 2001 From: "Kawai, Hidehiro" Date: Thu, 19 Jul 2007 01:48:27 -0700 Subject: coredump masking: reimplementation of dumpable using two flags This patch changes mm_struct.dumpable to a pair of bit flags. set_dumpable() converts three-value dumpable to two flags and stores it into lower two bits of mm_struct.flags instead of mm_struct.dumpable. get_dumpable() behaves in the opposite way.
