      Introduced directory quota as hard limits on the number of names in the tree rooted at that directory. An administrator may set quotas on individual directories explicitly. Newly created directories have no associated quota. File/directory creations fault if the quota would be exceeded. The attempt to set a quota faults if the directory would be in violation of the new quota.
