From 6174eafce3a38114adc6058e2872434c53feae87 Mon Sep 17 00:00:00 2001 From: James Carter Date: Wed, 4 Apr 2007 16:18:39 -0400 Subject: selinux: explicitly number all selinuxfs inodes Explicitly number all selinuxfs inodes to prevent a conflict between inodes numbered using last_ino when created with new_inode() and those labeled explicitly.
