# 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'.
