Interesting. So whenever anyone accesses a directory, this triggers an
in-memory search of the list of mount points to see if there is a match?

Do systems with heavy activity tend to mount disks with the most
activity first to reduce average search time ? or does the in-kernel
structures gets sorted in some way, and the order in whic you mount them
becomes irrelevant ?
