syz.5.18581/17812 is trying to acquire lock:

but task is already holding lock:

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:
  &oi->ip_io_mutex --> &ocfs2_sysfile_lock_key[args->fi_sysfile_type]#4 --> &ocfs2_sysfile_lock_key[args->fi_sysfile_type]#3

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&ocfs2_sysfile_lock_key[args->fi_sysfile_type]#3);
                               lock(&ocfs2_sysfile_lock_key[args->fi_sysfile_type]#4);
                               lock(&ocfs2_sysfile_lock_key[args->fi_sysfile_type]#3);
  lock(&oi->ip_io_mutex);
