Hi James, this is a patchset to address the outstanding 'sdev oops during scanning' issue. Problem is that any sdev in state 'SDEV_DEL' is still visible to the host until the refcount drops to zero. When a scan occurs during this time we access a half-initialized sdev and all hell breaks loose. So to address this issue this patchset implements a 'scsi_resurrect_device()' function which will put an sdev in state SDEV_DEL back to SDEV_RUNNING, thus allowing normal operations again. In doing so I also had to clean up the sdev allocation and removal a bit so that we're now more aligned to the state machine and the driver core's device_initialize / device_add logic. The entire patchset has been tested quite heavily with SLES10 SP1. Comments etc. welcome. Otherwise, please apply.
