mariadb/mysql-test/r/ndb_condition_pushdown.result
unknown 59eaf292de Fixed compiler and valgrind warnings
Added missing DBUG_xxx_RETURN statements
Fixed some usage of not initialized variables (as found by valgrind)
Ensure that we don't remove locked tables used as name locks from open table cache until unlock_table_names() are called.
This was fixed by having drop_locked_name() returning any table used as a name lock so that we can free it in unlock_table_names()
This will allow Tomas to continue with his work to use namelocks to syncronize things.

Note: valgrind still produces a lot of warnings about using not initialized code and shows memory loss errors when running the ndb tests
