Virtual SSD not detected properly in Linux (Mint 17.2 and Manjaro 16.08)

[HaleTom]

I'm running VMware Workstation 12.5.1, and am trying to haveSCSI0:0 as an SSD drive.

(I want to have the discard mount option and fstrim / work on ext4 and btrfs.)

I added the following to my .vmx file: scsi0:0.virtualSSD = 1

But in Linux (both Mint 17.2 and Manjaro 16.08, /sys/block/sda/queue/rotational contains 1, meaning it's not a spindle and platter disk.

However, smartctl -a /dev/sda disagrees:

smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.16.0-38-generic] (local build)

How do I get rotational to be 0 (and thence get TRIM working?)

If there is no solution here, where should I raise this upstream?

It seems that Vbox fixed the analogous issue 3 years ago:
