Collaboration diagram for vfs_node:

Data Fields
const char *	name
	Canonical absolute path, such as `/dev/uart0`.

vfs_ops_t	ops
	Device operations.

void *	driver_data
	Driver-private state.

vfs_node_t *	next
	Namespace list link, managed by the VFS.

bool	is_directory
	The node is a directory.

bool	is_regular
	The node is a RAM file managed by the VFS.

bool	is_owned

Detailed Description

Named entry in the VFS namespace.

Drivers define device nodes statically, setting name, ops, and optionally driver_data, and pass them to vfs_register_node(). The VFS manages the other fields.

Field Documentation

◆ name

const char* vfs_node::name

Canonical absolute path, such as /dev/uart0.

Must outlive registration.

◆ driver_data

void* vfs_node::driver_data

Driver-private state.

For RAM files, the VFS-owned heap contents.

◆ is_regular

bool vfs_node::is_regular

The node is a RAM file managed by the VFS.

Device drivers leave it false.

◆ is_owned

bool vfs_node::is_owned

The VFS allocated the node and frees it on removal.

Drivers leave it false.

◆ size

unsigned vfs_node::size

RAM file length in bytes.

Unused for devices and directories.
