There's nothing Linux can do for today's Hyper-V passthrough wrt to
automatically turning on discard on my SATA SSD.
Martin explained that vendors often disable UNMAP/WRITE SAME to DSM TRIM
translation on purpose and/or have explicit device whitelists/blacklists
for those devices they want to support. It could be that Microsoft are
doing something similar (although it might be interesting to know how a
Windows 2012 guest on Hyper-V handles things).
