--------------------------------------------
syz.0.711/9147 is trying to acquire lock:

ffff88805bc8b468 (&ni->ni_lock#3/5){+.+.}-{3:3}, at: mi_read+0x466/0x660 fs/ntfs3/record.c:148

but task is already holding lock:

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

       CPU0
       ----
  lock(&ni->ni_lock#3/5);
  lock(&ni->ni_lock#3/5);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
