--------------------------------------------
syz.1.7/3662 is trying to acquire lock:

ffff8880627d9e80 (&ni->ni_lock/4){+.+.}-{3:3}, at: mi_read+0x2dd/0x5a0 fs/ntfs3/record.c:148

but task is already holding lock:

 (&ni->ni_lock/4){+.+.}-{3:3}, at: ntfs_lookup+0xf5/0x1f0 fs/ntfs3/namei.c:82

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

       CPU0
       ----
  lock(&ni->ni_lock/4);
  lock(&ni->ni_lock/4);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
