Subject: [PATCH 0/5] SCSI and FireWire: fix/add START STOP UNIT for SBP-2
 disks

This series contains:

Patch 1/5...3/5:  Some SBP-2 disks don't work as expected if the power
condition field in the START STOP UNIT command is not set.  They either
don't spin down on start=0, or they become unresponsive after it.  These
patches selectively adds power condition values for known affected
devices.  We can't do so across the board because certain other SBP-2
devices have been found to not support power condition (even though it
is mandatory as per RBC).

These three patches should IMO go into mainline during the current -rc
phase.

Patch 4/5...5/5:  Enable scsi_device.manage_start_stop for all SBP-2
devices (except if logged in non-exclusively).  This lets FireWire disks
spin down on suspend, driver unbinding, or system shutdown.

These two patches are post 2.6.26 material.

James, how do we handle patch 1/5, assumed that this one is OK?  Do you
route it through scsi-rc-fixes (or scsi-misc if really necessary), or do
you make an exception and let it slip through linux1394-2.6.git?  The
patch applies to plain 2.6.25 as well as to current scsi-misc without
conflicts.
