The log tables are by nature PERFORMANCE_SCHEMA tables, which should not be affected by SET GLOBAL READ_ONLY or FLUSH TABLES WITH READ LOCK. The implementation of FLUSH TABLES WITH READ LOCK already ignored log tables. Now with this patch, the implementation of LOCK TABLE also ignore a global read lock for log tables, which was the missing symmetry.
