Description

bb-10.6-release 02e97252
safe_mutex: Found wrong usage of mutex 'LOCK_thd_data' and 'wait_mutex'
Mutex currently locked (in reverse order):
wait_mutex /data/src/10.6/storage/innobase/handler/ha_innodb.cc line 5024
LOCK_thd_data /data/src/10.6/sql/sql_class.h line 3851
LOCK_thd_kill /data/src/10.6/sql/sql_class.h line 3850

The failure started happening after this commit in 10.6

    MDEV-32096 Parallel replication lags because innobase_kill_query() may fail to interrupt a lock wait

That's expected, as the mutex lock was only added there.
Since the same test doesn't trigger any other failures for me on a build before the commit, I'll consider it a regression for now. Feel free to demote if the analysis shows otherwise.
