>
> Have PoolBasedHierarchicalResourceLockManager which would implement the classÂ
> HierachicalResourceLockManager backed by generic object pool and
> ConcurrentHashMap enabling acquiring read write locks on resources with a
> deterministic order which is not possible with a stripe based locking.
> This is required for acquiring locks on chain while iterating through the
> snapshot chain.
> FYI this can be reused for FSO path locking while path resolution.
