I'll agree with Greg that it's not optimal. Life changes, and in a few
years you might move on and no longer be interested in ReiserFS. That
will make it very hard to stay in sync over the long term. However, if
this is to be the basis for doing a GPL-free version of ReiserFS, then
there is nothing wrong with changing the layout. I guess it all comes
down to what your long-term plans and committments are. If what you
have now is what you are comfortable with and you have plans to continue
to maintain and improve it, then by all means import it.
