Chapter 21. Mount Table

The

data

field is a private data value. This may be installed either statically when the table entry is defined, or

may be installed during the

mount()

operation.

The

valid

field indicates whether this mount point has actually been mounted successfully. Entries with a false

valid

field are ignored when searching for a name match.

The

field is installed after a successful

mount()

operation to point to the implementing filesystem.

The

root

field contains a directory pointer value that the filesystem can interpret as the root of its directory tree.

This is passed as the

dir

argument of filesystem functions that operate on rooted filenames. This field must be

initialized by the filesystem’s

mount()

function.
