I'm not suggesting we get rid of 'version' in the actual nodes.
As I understand this adding 'version' to struct jffs2_raw_node_ref
increases the RAM usage by N*(X+Y) where:
N is the size of the version field
X is the number of direnties
Y is the number of data nodes
It seems there "ought" to be a way to only increase RAM size by N*X.
I'm assuming Y>>X so this could be a big factor for RAM usage.
Am I missing something?
