+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.
