Remove incorrect BF (brute force) handling from lock_rec_has_to_wait_in_queue and move condition to correct callers. Add a function to report BF lock waits and assert if incorrect BF-BF lock wait happens. wsrep_report_bf_lock_wait Add a new function to report BF lock wait. wsrep_assert_no_bf_bf_wait Add a new function to check do we have a BF-BF wait and if we have report this case and assert as it is a bug. lock_rec_has_to_wait Use new wsrep_assert_bf_wait to check BF-BF wait. lock_rec_create_low lock_table_create Use new function to report BF lock waits. lock_rec_insert_by_trx_age lock_grant_and_move_on_page lock_grant_and_move_on_rec Assert that trx is not Galera as VATS is not compatible with Galera. lock_rec_add_to_queue If there is conflicting lock in a queue make sure that transaction is BF. lock_rec_has_to_wait_in_queue Remove incorrect BF handling. If there is conflicting locks in a queue all transactions must wait. lock_rec_dequeue_from_page lock_rec_unlock If there is conflicting lock make sure it is not BF-BF case. lock_rec_queue_validate Add Galera record locking rules comment and use new function to report BF lock waits. All attempts to reproduce the original assertion have been failed. Therefore, there is no test case on this commit.
