Hi Zdenek, I am not sure about what bug I found - can you be more 
explicit?

Again, I am not sure about what we are speaking - generic thinlvm over 
VDO, or about the caching issue discussed before? Why this should be an 
issue for XFS vs EXT4? From RH docs, I can see VDO + thinlvm + XFS as 
being fully supported.

I'll do, but I first need to understand the core issue better.
Thanks.
