--------------------------------------------
syz.0.0/5325 is trying to acquire lock:

but task is already holding lock:
ffff8880454fef28 (&ni->ni_lock#3/5){+.+.}-{3:3}, at: ni_lock fs/ntfs3/ntfs_fs.h:1109 [inline]
ffff8880454fef28 (&ni->ni_lock#3/5){+.+.}-{3:3}, at: ntfs_rename+0x74a/0xd10 fs/ntfs3/namei.c:312

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
