Merge following change from 10.2 revision-id: d52cff9f10aeea208a1058f7b5527e602125584c (mariadb-10.2.14-25-gd52cff9) parent(s):bc2501453cauthor: Sachin Setiya committer: Sachin Setiya timestamp: 2018-04-04 12:26:06 +0530 message: MDEV-15611 Due to the failure of foreign key detection, Galera... slave node killed himself. Problem:- If we try to delete table with foreign key and table whom it is referring with wsrep_slave_threads>1 then galera tries to execute both Delete_rows_log-event in parallel, which should not happen. Solution:- This is happening because we do not have foreign key info in write set. Upto version 10.2.7 it used to work fine. Actually it happening because of issue in commit2f342c4. wsrep_must_process_fk should be used with negation.
