Fstrim destroys data on loopback device
I have attempted to reproduce this on both Utopic and Trusty (14.04)
without success, below is a transcript of my attempt on Trusty. This is
with the latest Trusty main kernel. Perhaps you could confirm this
script correctly repeats your reproduce steps. If so then there must be
a system
Here is the actual script i am using to implement your reproduction
script in the description.

It appears you are currently running a mainline kernel
I've upgraded to mainline kernel 3.17.1-031701-generic #201410150735, thought
it maybe contains a bugfix for this.
