JFFS2 mount time - 3 more questions

[Ferenc Havasi]

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,
