From c56050c700d18f18fbec934f56069150bcec3709 Mon Sep 17 00:00:00 2001 From: Chun Chen Date: Mon, 9 Nov 2015 14:58:15 -0800 Subject: Documentation/sysctl/vm.txt: fix misleading code reference of overcommit_memory The origin document references to cap_vm_enough_memory is because cap_vm_enough_memory invoked __vm_enough_memory before and it no longer does now.
