[PATCH] Miscellaneous bug and warning fixes
This patch fixes a couple of bugs revealed in new features recently
added to -mm1:
* fixes warnings due to inconsistent use of const struct inode *inode
* fixes bug that prevent a kernel from booting with audit on, and SELinux off
due to a missing function in security/dummy.c
* fixes a bug that throws spurious audit_panic() messages due to a missing
return just before an error_path label
* some reasonable house cleaning in audit_ipc_context(),
audit_inode_context(), and audit_log_task_context()
