Subject: calculate actual state of caches wrt set of files/dirs, without modifying caches ?

Is it possible to calculate the following thing from userspace:
Some benchmarking program has list of filenames and dirnames.
Can it calculate how many of inodes and data blocks of those items are *cached*
vs how many are not, without modifying existing
status of inode caches & buffer caches ?

Thanks
Yakov
