WARNING: possible recursive locking detected
6.1.115-syzkaller #0 Not tainted
--------------------------------------------
syz.3.781/7601 is trying to acquire lock:
ffff888058252d40 (&ni->ni_lock/4){+.+.}-{3:3}, at: ni_lock fs/ntfs3/ntfs_fs.h:1101 [inline]
ffff888058252d40 (&ni->ni_lock/4){+.+.}-{3:3}, at: mi_read+0x2dd/0x5a0 fs/ntfs3/record.c:148

but task is already holding lock:
ffff888058251720 (&ni->ni_lock/4){+.+.}-{3:3}, at: ni_lock fs/ntfs3/ntfs_fs.h:1101 [inline]
ffff888058251720 (&ni->ni_lock/4){+.+.}-{3:3}, at: ntfs_link+0xf0/0x280 fs/ntfs3/namei.c:149

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
