Basically, attempts to access a non-existent directory in multi-mount tree leads to a negative dentry being sent to the wait queue, but v5 direct and offset mounts must always have an existing (non-negative dentry) directory upon which to mount. This is only relevant for multi-mounts that don't have an explicit multi-mount root so that the lookups occur within the autofs file system. Sorry, I still can't think of a way to avoid this for v4.
