It would be nice to allow the parted interface of reiserfs to support any extra features that reiser might have over other FSes.  This is something we can toss into the vfs interface.  Possibly another routine that the PedFileSystemOps could contain.  Such routine would allow any extra features outside of standard mkpartition, resize, etc etc to be conducted.

While I like the idea to be more flexible as possible, I also think it
adds complexity and sometimes we won't use it in near future and the
tradeof for supporting it now might not be that good.

I'm not saying that this is the case but if it starts to look to be
too complicate, let's ignore it for now and come back to it once
needed.
