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.
