# === Purpose ===
# Check FLUSH BINARY LOGS operation is mutually exclusive with BACKUP lock.
#
# === Requirements ===
# R1. FLUSH BINARY LOGS must be mutually exclusive with BACKUP operation.
#
# === Implementation ===
# 1. Initialize
# 2. Execute FLUSH BINARY LOGS but stop on 'at_purge_logs_before_date' sync point
# 3. Check errors for LOCK INSTANCE FOR BACKUP operation
# 4. Continue FLUSH BINARY LOGS operation
# 5. Check no errors for LOCK INSTANCE FOR BACKUP operation
#
# === References ===
#
# Bug#35342521 Binary log purge should hold IX backup lock
