Comment by Marko Mäkelä [ 2020-12-03 ]

Starting with MariaDB 10.2.2, INFORMATION_SCHEMA.INNODB_MUTEXES only reported information about rw-locks, not mutexes. The rw-lock output was removed in MariaDB 10.6.0 in MDEV-24167 and MDEV-24142, and the entire view INFORMATION_SCHEMA.INNODB_MUTEXES was removed in MDEV-24142.
