Actually, that's something that autofs v3 *does* keep in the dentry; by
keeping a negative dentry which eventually gets invalidated (by using a
timer.) That works great in the case of requests that fail quickly. I
don't worry too much about stuff that fail during mount, since the mount
tends to be a rate limiter anyway.
