Have no idea :) I do not know anything about Dr. Orlando and his crew.
Suff itself is not difficult, as there is not tree modifications, etc.

Rough sequence is like this:

(1) make sure, that there is no not replied transactions.

(2) tree traverse and move all nodes and unformatted blocks which do not=20
fit to new range (new_start - new_end) one by one to new area. Block=20
allocator info should be updated on this stage too.

(3) update some fields in super block. Probably one more update of block=20
allocator.

The framework for all these actions exists in libreiser4.

Parted's part is trivial -- just follow the API.
