WARNING: possible recursive locking detected
syzkaller #0 Not tainted
--------------------------------------------
syz.0.0/5320 is trying to acquire lock:
ffff88801f4db430 (&ni->ni_lock/5){+.+.}-{4:4}, at: ni_lock fs/ntfs3/ntfs_fs.h:1217 [inline]
ffff88801f4db430 (&ni->ni_lock/5){+.+.}-{4:4}, at: mi_read+0x2dd/0x5b0 fs/ntfs3/record.c:148

but task is already holding lock:
ffff8880478e8850 (&ni->ni_lock/5){+.+.}-{4:4}, at: ni_lock fs/ntfs3/ntfs_fs.h:1217 [inline]
ffff8880478e8850 (&ni->ni_lock/5){+.+.}-{4:4}, at: ntfs_link+0xf6/0x280 fs/ntfs3/namei.c:141

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

       CPU0
       ----
  lock(&ni->ni_lock/5);
  lock(&ni->ni_lock/5);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
