I belive this is not clear enough from the documentation and the
instructions on <URL: http://wiki.debian.org/SSDOptimization >.  But I
am unsure how to make it more clear. :/

I must admit that <URL:https://bugs.debian.org/717313#36 > describe my
expectations too.  There, Ralf Jung stated

  "You can get your data back after you explicitly told the system, as
  root, to delete it" is not a feature that anybody should expect, and
  it should only be considered if it can be provided without significant

I expect that the SSD releases the storage when I remove a LV, not that
I can get it back.

Happy hacking
