Yes, summary will help greatly with mount time, but unfortunately it 
doesn't help with memory consumption and iget() (in Sergey's case the time 
of the background checking is the same).

Albeit I used to claim it is a good attribute not to check CRCs for
blocks with summaries, now I believe it is wrong and dangerous and must 
not be used in JFFS2.
