From 0406289ed57955860a4f8d744a14f4c819260ce4 Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Wed, 1 Oct 2008 12:42:20 +0200 Subject: [SCSI] zfcp: Simplify zfcp data structures Reduce the size of zfcp data structures by removing unused and redundant members. scsi_lun is only the mangled version of the fcp_lun. So, remove the redundant field and use the fcp_lun instead. Since the queue lock and the pci_batch indicator are only used in the request queue, move them from the common queue struct to the adapter struct.
