--------------------------------------------
syz-executor/4024 is trying to acquire lock:
ffff0000cb8be990 (jbd2_handle){++++}-{0:0}, at: jbd2_log_wait_commit+0x130/0x42c fs/jbd2/journal.c:696

but task is already holding lock:
ffff0000cb8be990 (jbd2_handle){++++}-{0:0}, at: start_this_handle+0xecc/0x11a4 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
