WARNING: possible recursive locking detected
syzkaller #0 Not tainted
--------------------------------------------
syz.3.75/7050 is trying to acquire lock:
ffff0000f7179e20 (&ni->ni_lock#2/5){+.+.}-{4:4}, at: ni_lock fs/ntfs3/ntfs_fs.h:1113 [inline]
ffff0000f7179e20 (&ni->ni_lock#2/5){+.+.}-{4:4}, at: mi_read+0x258/0x4cc fs/ntfs3/record.c:148

but task is already holding lock:

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

       CPU0
       ----
  lock(&ni->ni_lock#2/5);
  lock(&ni->ni_lock#2/5);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
