[SCSI] modify change_queue_depth to take in reason why it is being called
This patch modifies scsi_host_template->change_queue_depth so that it takes an argument indicating why it is being called. This will be used so that if a LLD needs to do some extra processing when handling queue fulls or later ramp ups, it can do so. This is a simple port of the drivers setting a change_queue_depth callback. In the patch I just have these LLDs adjust the queue depth if the user was requesting it. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> [Vasu.Dev: v2 Also converted pmcraid_change_queue_depth and then verified all modules compile using "make allmodconfig" for any new build warnings on X86_64. Updated original description after combing two original patches from Mike to make this patch git bisectable.] Signed-off-by: Vasu Dev <vasu.dev@intel.com> [jejb: fixed up 53c700] Signed-off-by: James Bottomley <James.Bottomley@suse.de>
