File size limitation on JFFS2.

[Han Chang]

David,

Thanks for the info. I'm using 2.6.14. Moving to a 2.6.18-rc1 will be a too 
big of change for me unless it's absolutely necessary. I'm very interested 
in the knowing how to move to 32KiB node. Could you shed some light on this?

Many thanks!
Han
