Hi Tejun,
Thanks for the fast response and action.

it. I'll come up with a patch, please wait a bit before releasing the
update.
The patch has been merged into libata-dev.git so I'd like to revisit
this topic now.
Am I right in saying, to fix 2.6.21, the following patches are needed,
and no others, in this order:
sd: fix return value of sd_sync_cache()
3721050afc6cb6ddf6de0f782e2054ebcc225e9b
(not sure if this one is required?)
[SCSI] sd: implement START/STOP management
3c94c5a2fb43a654e777f509d5032b0db8ed09f
libata: reimplement suspend/resume support using sdev->manage_start_stop
9666f4009c22f6520ac3fb8a19c9e32ab973e828
libata: implement libata.spindown_compat
920a4b1038e442700a1cfac77ea7e20bd615a2c3
libata: fix shutdown warning message printing
da071b42f73dabbd0daf7ea4c3ff157d53b00648
libata: track spindown status and skip spindown_compat if possible
13b8d09f5de0aaa3153bbccc98baf247387823dc
Additionally, no userspace modifications are needed, at least while
Gentoo's shutdown/halt programs are not attempting to spin down libata
disks?
I note that the patch titled "SCSI: kill sht->suspend/resume" (not
included in the above tree) is not yet merged into Linus' tree. Am I
right in saying it's not required for the disk spindown stuff to work
properly?
Thanks!
Daniel
