I'm doing some research with servers and would like to know if there's
any reasonable way to determine which files or blocks of files are being
cached at any given time. If there isn't a way right now, how feasible
would it be to hack a module to create an interface for this.
Thank you,
Chase Douglas

which files is hard currently; which blocks of a file you can get by
mmaping the file and then using the mincore() syscall..
