Not following here. fs_on_ssd() will actually check for the high-level
ID_SSD property, as well as the "queue/rotational" sysfs attribute for
the block device.

Are you saying that on you machine queue/rotational is set to 1 for
MMCs? If so, this appears to be the more appropriate thing to fix?

Moreover, why is this supposedly ARM specific?
