Hi Artem,

It heavily depends on
- the size of the earase block
- the sizes of the nodes
It is 4 words for every jffs2_raw_inode. Dirents are stored separatedly
without summary.

To make boot time as fast as possible :) But not a bad idea. If someone
needs it we can make a new option.

I think it is "nicer", cleaner design, and uing this separation the
reordering of the nodes is much more easier.
Bye,
Ferenc
