Invalidate all references to a vnode.
- macOS 10.4+
The vnode to revoke.
Context against which to validate operation.
Reclaims the vnode, giving it deadfs vnops (though not halting operations which are already in progress). Also reclaims all aliased vnodes (important for devices). People holding usecounts on the vnode, e.g. processes with the file open, will find that all subsequent operations but closing the file fail.
