    4341If the argument is a file path, VFS uses the ''vfs_lookup_internal()'' function to
    4442translate the path into the so called lookup result represented by the ''vfs_lookup_res_t''
    … …  
    5957VFS keeps information about each referenced file in an abstraction called VFS
    6058node, for which there is the ''vfs_node_t'' type. Thus, a VFS node represents
    61 some file which is referenced by VFS.
     59some file which is referenced by VFS. VFS nodes are the first class entities
     60in the VFS server, because in most operations, a VFS node must be instantiated.

    6362The VFS server calls the ''vfs_node_get()'' function in order to get a VFS node
