Subject: [PATCH] Fix suid_dumpable and lease-break-time sysctls
Date: Fri, 27 Mar 2009 07:31:39 -0600 [thread overview]
Message-ID: <20090327133138.GJ8014@parisc-linux.org> (raw)
Arne de Bruijn points out in Bugzilla 12953 that commit
76fdbb25f963de5dc1e308325f0578a2f92b1c2d mistakenly limits
lease-break-time instead of suid_dumpable.
