Thats right , but after that caching , for example if you load couple big (x) files into memory , kernel will slightly push oldest cache away , instead of our expecting pushing old (x) cached file and keep /usr cache in memory
Anyways you are right , cat the whole /usr section in a way
Any other ideas ?
