    Description

      WT-3766 enables the LAS sweep to remove the LAS entries that are no longer required. But the LAS sweep is not removing any the LAS entries when there is no table is removed from the WiredTiger. In function __las_sweep_init, the cache->las_sweep_max_pageid is not set when there are no tables removed from the WiredTiger. The same variable is checked for validity while performing the LAS sweep whether the sweep can proceed or not? Because of this reason, the no LAS entries are removed when there are no tables removed.
