--------------------------------------------
syz.4.29/6133 is trying to acquire lock:
ffff8880771ce7d0 (&ni->ni_lock#3/5){+.+.}-{4:4}, at: ni_lock fs/ntfs3/ntfs_fs.h:1105 [inline]
ffff8880771ce7d0 (&ni->ni_lock#3/5){+.+.}-{4:4}, at: mi_read+0x2e1/0x5a0 fs/ntfs3/record.c:148

but task is already holding lock:
ffff88805332d1c8 (&ni->ni_lock#3/5){+.+.}-{4:4}, at: ni_lock fs/ntfs3/ntfs_fs.h:1105 [inline]
ffff88805332d1c8 (&ni->ni_lock#3/5){+.+.}-{4:4}, at: ntfs_rename+0x78c/0xd40 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
