--------------------------------------------
syz-executor/4031 is trying to acquire lock:
ffff0000eb5b0990 (jbd2_handle){++++}-{0:0}, at: jbd2_log_wait_commit+0x138/0x448 fs/jbd2/journal.c:697

but task is already holding lock:
ffff0000eb5b0990 (jbd2_handle){++++}-{0:0}, at: start_this_handle+0xf98/0x12a4 fs/jbd2/transaction.c:462

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(jbd2_handle);
  lock(jbd2_handle);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
