From 8e654fba4a376f436bdfe361fc5cdbc87ac09b35 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Thu, 2 Apr 2009 16:58:33 -0700 Subject: sysctl: fix suid_dumpable and lease-break-time sysctls Arne de Bruijn points out that commit 76fdbb25f963de5dc1e308325f0578a2f92b1c2d ("coredump masking: bound suid_dumpable sysctl") mistakenly limits lease-break-time instead of suid_dumpable.
