> {{FSDirectory#getFileEncryptionInfo}} always acquires {{readLock}} and checks if the
path belongs to an EZ. For a busy system with potentially many listing operations, this could
cause locking contention.
> I think we should add a call {{EncryptionZoneManager#hasEncryptionZone()}} to return
whether the system has any EZ. If no EZ at all, {{getFileEncryptionInfo}} should return null
without {{readLock}}.
> If {{hasEncryptionZone}} is only used in the above scenario, maybe itself doesn't need
a {{readLock}} -- if the system doesn't have any EZ when {{getFileEncryptionInfo}} is called
on a path, it means the path cannot be encrypted.
