Detailed Description

Closing a vnode: dropping a reference to it.

Definition in file close.c.

Function Documentation

vfs_close()

int vfs_close

(

struct vnode *

vnode

)

Drops a reference to a vnode.

When the last one goes, the filesystem's close operation releases it. Closing a vnode that has no references left is a bug, and panics.

Parameters

vnode

the vnode

Returns

0, -EINVAL if vnode isn't a valid vnode, or what the filesystem's close operation returns
