:Now we deal with collapsing of layers:
Anything that you can trivially collapse is a degenerate case and thus
a relatively easy problem to solve no matter what design you use. Even
the current design can almost handle it. Using NullFS as example is
ridiculous -- NullFS is about as degenerate as case as you can get.
Using it to prove a point makes no sense. Use something complex that
requires cache coherency and prove your point with that - except you
refuse to consider any stacking cases where cache coherency might be
an issue.
