  libata-acpi: clean up parameters and misc stuff
  libata-acpi: s/CONFIG_SATA_ACPI/CONFIG_ATA_ACPI/
  libata: give devices one last chance even if recovery failed with -EINVAL
  libata: fallback to the other IDENTIFY on device error, take#2
  libata: ignore EH scheduling during initialization
  libata: clean up SFF init mess
  libata: implement libata.spindown_compat
  libata: reimplement suspend/resume support using sdev->manage_start_stop

 ---------------------------
 
+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.
