Monty 5e40934d24 MDEV-28897 Wrong table.get_ref_count() upon concurrent truncate and backup stage operation
The issue was that flush_tables() didn't take a MDL lock on cached
TABLE_SHARE before calling open_table() to do a HA_EXTRA_FLUSH call.
Most engines seams to have no issue with it, but apparantly this conflicts
with InnoDB in 10.6 when using TRUNCATE

Fixed by taking a MDL lock before trying to open the table in
flush_tables().

There is no test case as it hard to repeat the scheduling that causes
the error. I did run the test case in MDEV-28897 to verify
that the bug is fixed.

MariaDB: The open source relational 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.
