3.16.61-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Kiran Kumar Modukuri <kiran.modukuri@xxxxxxxxx> commit d0eb06afe712b7b103b6361f40a9a0c638524669 upstream. Alter the state-check assertion in fscache_enqueue_operation() to allow cancelled operations to be given processing time so they can be cleaned up. Also fix a debugging statement that was requiring such operations to have an object assigned.
