From efc3c1df5fda0aee84f53c226d55804e6dbede4f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 24 Nov 2014 15:36:18 +0100 Subject: scsi: remove ->change_queue_type method Since we got rid of ordered tag support in 2010 the prime use case of switching on and off ordered tags has been obsolete. The other function of enabling/disabling tagging entirely has only been correctly implemented by the 53c700 driver and isn't generally useful.
