Would it be possible to create a mount option (or something else) which would only cache disk blocks from directories and not disk blocks from 'normal' files? Or give the former precedence over the latter for staying in the buffer cache? The reason why I'm asking this? I'm currently playing with the Squid proxy-cache to improve its usage of the file system cache. For applications like Squid it's very important to keep as much directory blocks in the buffer cache as possible. Caching of 'normal' files doesn't make any sense because Squid has its own hot-object cache and most file access is too random anyway in order for the buffer cache to be useful.
