From c40ecc12cfdb630332198a04e2832ae8218a61f1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 13 Nov 2014 14:25:11 +0100 Subject: scsi: avoid ->change_queue_depth indirection for queue full tracking All drivers use the implementation for ramping the queue up and down, so instead of overloading the change_queue_depth method call the implementation diretly if the driver opts into it by setting the track_queue_depth flag in the host template. Note that a few drivers validated the new queue depth in their change_queue_depth method, but as we never go over the queue depth set during slave_configure or the sysfs file this isn't nessecary and can safely be removed.
