Reduce the number of nodes purged from the dir-cache when ForgetPath is called. This is done by only forgetting the cache of the received path and invalidating the parent folder cache by resetting *Dir.read. The parent will read the listing on the next access and reuse the dir-cache of entries in *Dir.items.
