Non-rotational media would tend to want the unplugging, but the block

so non-rotational devices get unplugged whether the request was a
unplugging request or not).

Mmm.. except that Jeff's SSD doesn't appear to identify itself
as a non-rotating media. I suppose there's a way to "quirk" that
somewhere, though.
We set it in libata-scsi.c:ata_scsi_dev_config() based on ata_id_is_ssd()
That hueristic probably assumes Intel SSDs or something :/
