-What: libata.spindown_compat module parameter
+What: libata spindown skipping and warning
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.
+Why: Some halt(8) implementations synchronize caches for and spin

+ Spin down on system halt is now implemented. sysfs node
+ /sys/class/scsi_disk/h:c:i:l/manage_start_stop is present if
+ spin down support is available.
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.
