--------------------------------------------
syz-executor.5/13473 is trying to acquire lock:
ffff88803a3e1720 (&ni->ni_lock#2){+.+.}-{3:3}, at: ntfs_set_state+0x1ff/0x6b0 fs/ntfs3/fsntfs.c:946

but task is already holding lock:

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

       CPU0
       ----
  lock(&ni->ni_lock#2);
  lock(&ni->ni_lock#2);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
