  BUG#11704: Make InnoDB not to convert TL_WRITE_ONLY locks to TL_WRITE_ALLOW_WRITE in 
  OPTIMIZE TABLE.

  sql/ha_innodb.cc
    1.274 05/10/25 00:27:04 sergefp@stripped +1 -0
    Fix for BUG#11704: "Found locks from different thread" warnings:
    The source of warnings was this scenario in OPTIMIZE:
      thr1: lock table with TL_WRITE_ONLY (InnoDB converts lock to TL_WRITE_ALLOW_WRITE)
      thr2: (UPDATE command) obtains a TL_WRITE_ALLOW_WRITE lock
      thr1: call mysql_lock_abort(). This function sets type of thr'1 lock to TL_WRITE_ONLY
      thr2: try to release thr2's lock. See two locks: TL_WRITE_ONLY, TL_WRITE_ALLOW_WRITE 
            and produce a warning.
    
    The fix: Make InnoDB not to convert TL_WRITE_ONLY locks to TL_WRITE_ALLOW_WRITE in
    OPTIMIZE TABLE.
