From 119f657c72fc07d6fd28c61de59cfba1566970a9 Mon Sep 17 00:00:00 2001 From: "akpm@osdl.org" Date: Sun, 1 May 2005 08:58:35 -0700 Subject: [PATCH] RLIMIT_AS checking fix Address bug #4508: there's potential for wraparound in the various places where we perform RLIMIT_AS checking. (I'm a bit worried about acct_stack_growth(). Are we sure that vma->vm_mm is always equal to current->mm? If not, then we're comparing some other process's total_vm with the calling process's rlimits).
