@chapter Filesystem Lifecycle
|
|
|
|
This chapter describes some of the dynamic behavior of file system control
|
|
structures
|
|
|
|
@section Mount table chain
|
|
|
|
The mount table chain is a dynamic list of structures that describe
|
|
mounted file systems a specific points in the file system hierarchy. It is
|
|
initialized to an empty state during the base file system initialization.
|
|
The mount operation will add entries to the mount table chain. The
|
|
un-mount operation will remove entries from the mount table chain.
|
|
|
|
@section Memory associated with the In Memory Filesystem
|
|
|
|
A memory based file system draws its resources for files and directories
|
|
from the memory resources of the system. When it is time to un-mount the
|
|
file system, the memory resources that supported file system are set free.
|
|
In order to free these resources, a recursive walk of the file systems
|
|
tree structure will be performed. As the leaf nodes under the file system
|
|
are encountered their resources are freed. When directories are made empty
|
|
by this process, their resources are freed.
