stats_deinit(): Replaces dict_stats_deinit(). Deinitialize the statistics for persistent tables, so that they will be reloaded or recalculated on a subsequent ha_innobase::open(). ha_innobase::rename_table(): Invoke stats_deinit() so that the subsequent ha_innobase::open() will reload the InnoDB persistent statistics. That is, it will remain possible to have the InnoDB persistent statistics reloaded by executing the following: RENAME TABLE t TO tmp, tmp TO t; dict_table_close(table): Replaced with table->release(). There will no longer be any logic that would attempt to ensure that the InnoDB persistent statistics will be reloaded after FLUSH TABLES has been executed. This also fixes the problem that dict_table_t::stat_modified_counter would be frequently reset to 0, whenever ha_innobase::open() is invoked after the table reference count had dropped to 0. dict_table_close(table, thd, mdl): Remove the parameter "dict_locked". Do not try to invalidate the statistics. ha_innobase::statistics_init(): Replaces dict_stats_init(table). Reviewed by: Thirunarayanan Balathandayuthapani

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:

Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
