USB storage suspend

Hi Alan,

What's the current state of USB mass storage suspend?  I know there was
some purposed changes to the SCSI or block layer that would have
effected suspend, and I wondered if those made it in.

I'm specifically looking for when we can expect a USB storage device to
go into auto-suspend.  If userspace enables auto-suspend and sets the
autosuspend_delay_ms to zero, could we see auto-suspend between SCSI
commands?  Or will the device remain in U0 until the storage device is
unmounted?
