 3215 Dmitry Lenev	2010-09-24
      Fix compile warning about passing NULL to non-pointer
      argument of inline_mysql_mutex_init in sql_base.cc.
      
      When initializing LOCK_dd_owns_lock_open mutex pass
      correct PSI key instead of NULL value.
     @ mysql-test/suite/perfschema/r/dml_setup_instruments.result
        Updated test results after adding P_S instrumentation
        for LOCK_dd_owns_lock_open.
     @ sql/sql_base.cc
        When initializing LOCK_dd_owns_lock_open mutex pass
        correct PSI key instead of NULL value.
