Considerations for filesystem resource managers

Since a filesystem resource manager may potentially receive long pathnames, it must be able to parse and handle each component of the path properly.

Let's say that a resource manager registers the mountpoint /mount/, and a user types:

ls -l /mount/home

where /mount/home is a directory on the device. The ls utility does the following:

d = opendir("/mount/home");
while (...) {
    dirent = readdir(d);
