What: libata.spindown_compat module parameter

When: Dec 2008

Why:  halt(8) synchronizes caches for and spins down libata disks

      because libata didn't use to spin down disk on system halt

      (only synchronized caches).

      Spin down on system halt is now implemented and can be tested

      using sysfs node /sys/class/scsi_disk/h:c:i:l/manage_start_stop.

      Because issuing spin down command to an already spun down disk

      makes some disks spin up just to spin down again, the old

      behavior needs to be maintained till userspace tool is updated

      to check the sysfs node and not to spin down disks with the

      node set to one.

      This module parameter is to give userspace tool the time to

      get updated and should be removed after userspace is

      reasonably updated.
