From e950598d43dce8d97e7d5270808393425d1e5cbd Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Tue, 31 Aug 2010 09:38:51 -0400 Subject: ima: always maintain counters commit 8262bb85da allocated the inode integrity struct (iint) before any inodes were created. Only after IMA was initialized in late_initcall were the counters updated. This patch updates the counters, whether or not IMA has been initialized, to resolve 'imbalance' messages. This patch fixes the bug as reported in bugzilla: 15673. When the i915 is builtin, the ring_buffer is initialized before IMA, causing the imbalance message on suspend.
