Reason for the change was that ha_notify_table_changed() was done after table open when .frm had been replaced, which caused failure in engines that checks on open if .frm matches the engines table definition. Other changes: - Remove not needed open/close call at end of inline alter table. Some test that depended on the table beeing in the table cache after ALTER TABLE had to be updated.
