From c5bf71a9a3b10c0cce877b7b3add4484322d3e2c Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 11 Jul 2011 15:02:24 +0200 Subject: scsi: Add 'hba_private' to SCSIRequest 'tag' is just an abstraction to identify the command from the driver. So we should make that explicit by replacing 'tag' with a driver-defined pointer 'hba_private'. This saves the lookup for driver handling several commands in parallel. 'tag' is still being kept for tracing purposes.
