  • Method and apparatus for enhanced performance caching for path names
    Patent number: 6535970
    Abstract: A method and apparatus are provided for enhanced performance caching for path names. A vnode is built for a root directory and a path name is stored in a path cache for the vnode for the root directory. A second vnode is built for a second directory and a path name is stored in a path cache for the second vnode. When a next vnode is built for a next directory, then a path name is stored in a path cache for the next vnode. For a given vnode, the path name includes an entire path name that leads to the vnode. A given vnode is enabled to return its entire path name in one step, without reverse traversal.
