WARNING: possible recursive locking detected
syzkaller #0 Not tainted
--------------------------------------------
syz.1.18/5980 is trying to acquire lock:
ffff8881a5953430 (&ni->ni_lock/5){+.+.}-{4:4}, at: ni_lock fs/ntfs3/ntfs_fs.h:1217 [inline]
ffff8881a5953430 (&ni->ni_lock/5){+.+.}-{4:4}, at: mi_read+0x2dd/0x5b0 fs/ntfs3/record.c:148

but task is already holding lock:
ffff8881a59596f0 (&ni->ni_lock/5){+.+.}-{4:4}, at: ni_lock fs/ntfs3/ntfs_fs.h:1217 [inline]
ffff8881a59596f0 (&ni->ni_lock/5){+.+.}-{4:4}, at: ntfs_rename+0x6a7/0xb40 fs/ntfs3/namei.c:327

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
