Subject: [PATCH v1 0/2] Add destructor hook to LSM modules


LSM security/integrity/iint.c had the case of kmem_cache_create() w/o a proper
kmem_cache_destroy() destructor.

Introducing the release() hook would enable LSMs to release allocated resources
on exit, and in proper order, rather than dying all together with kernel shutdown
in an undefined order.

Thanks,
	Mirsad
