+##############################################################################
+# BUG#48321 CURRENT_USER() incorrectly replicated for DROP/RENAME USER,
+# REVOKE, GRANT, ALTER EVENT
+#
+# Calling CURRENT_USER() results into inconsistency between slave and master,
+# as the slave SQL thread has different user with common users.
+#
+# After the patch for bug#48321, session's user will be written into query log
+# event if CURRENT_USER() is called in 'DROP/RENAME USER', 'REVOKE', 'GRANT',
+# 'ALTER EVENT'.
