From 1dfcda06a67d6ad6f890dbd1bab84be5f17ef46d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 21 Mar 2007 16:05:16 +0900 Subject: [SCSI] kill scsi host template suspend/resume With libata converted to use sdev->manage_start_stop for suspend and resume, sht->suspend/resume() has no user left and low level suspend/ressume should be taken care of by low level driver's suspend/resume callbacks (e.g. PCI or PCMCIA driver callbacks). This patch removes sht->suspend/resume() callbacks. This change is suggested by Christoph Hellwig.

This patch introduces a helper that does the cast called shost_priv. It's similar in spirit to netdev_priv for network drivers. This is the first patch introducing the macro, and the second patch in the series will convert esp and it's subdrivers as an example. Further conversion will wait until the helper is in the tree to make patch juggling easier.
