Well, thats quite an over simplification. You have a layered kernel API,
and the File System can introduce subtile asumptions which dont work on
virtual volumes. So especially the error handling, but also trivial
things as device discovery may not work out of the box with LVMs. And
then you get deeper stakcs and also all kind of possible races,
especially when kernel threads are involved. Do not even think about
trying it unless you are kernel hacker or it is oficially supported.
