    [SCSI] modify change_queue_depth to take in reason why it is being called · e881a172
    Mike Christie 提交于
    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.

    [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.]
