This is happening because IMA is not yet initialized when the IMA hook 
is called.

I had the following check in process_buffer_measurement() as part of my 
patch, but removed it since it is being upstreamed separately (by Mimi)

 if (!ima_policy_flag)
 	return;

Until this change is in, please add the above line locally on entry to 
process_buffer_measurement() to get around the issue.

thanks,
