◆ removeNode()

bool Iso9660Filesystem::removeNode	(	File *	parent,
		const String &	filename,
		File *	file
	)

protectedvirtual

Remove a backing node while the VFS holds the parent's namespace lock. A successful implementation must retire the parent's cached entry before returning and must recheck directory emptiness while holding the child's namespace lock.
