Is there also a (separate) dancing tree in memory? I ask this, because I'm not
sure, how squeezing and flushing is exactly done.
If I understood it well, then not just the filesystem tree, but also memory is
dancing (when data is squeezed)?
Thanks,
Marcel

Yes, reiser4 reads filesystem blocks into memory, links them into tree, modifies them and squeezes neighboring modified nodes before flushing to disk.
It may also flush them to different location on disk if it finds that more optimal.
