    Description

      A number of inefficiencies exist in EZ lookups. These are amplified by frequent operations like list status. Once one encryption zone exists, all operations take the performance penalty.

      Ex. Operations should not perform redundant lookups. EZ path reconstruction should be lazy since it's not required in the common case. Renames do not need to reallocate new IIPs to check parent dirs for EZ.
