11 | This chapter describes some of the dynamic behavior of file system control |

12 | structures |

14 | @section Mount table chain |
---|
15 | |
---|
16 | The mount table chain is a dynamic list of structures that describe |
---|
17 | mounted file systems a specific points in the file system hierarchy. It is |
---|
18 | initialized to an empty state during the base file system initialization. |
---|
19 | The mount operation will add entries to the mount table chain. The |
---|
20 | un-mount operation will remove entries from the mount table chain. |

22 | @section Memory associated with the In Memory File System |
---|
23 | |
---|
24 | A memory based file system draws its resources for files and directories |
---|
25 | from the memory resources of the system. When it is time to un-mount the |
---|
26 | file system, the memory resources that supported file system are set free. |
---|
27 | In order to free these resources, a recursive walk of the file systems |
---|
28 | tree structure will be performed. As the leaf nodes under the file system |
---|
29 | are encountered their resources are freed. When directories are made empty |
---|
30 | by this process, their resources are freed. |
