@ -206,24 +206,6 @@ Who: Len Brown <len.brown@intel.com>
---------------------------
What: libata spindown skipping and warning
When: Dec 2008
Why: Some halt(8) implementations synchronize caches for and spin
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. 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, libata tracks
device spindown status to skip the extra spindown command and
warn about it.
This is to give userspace tools the time to get updated and will
be removed after userspace is reasonably updated.
