Thomas Graf 80ca8c3a84 rhashtable: Lower/upper bucket may map to same lock while shrinking ... Each per bucket lock covers a configurable number of buckets. While shrinking, two buckets in the old table contain entries for a single bucket in the new table. We need to lock down both while linking. Check if they are protected by different locks to avoid a recursive lock.
