ntfs3: loop0: Mark volume as dirty due to NTFS errors
============================================
WARNING: possible recursive locking detected

--------------------------------------------
syz-executor309/5028 is trying to acquire lock:

ffff888076f01e80 (&ni->ni_lock/4){+.+.}-{3:3}, at: mi_read+0x2e1/0x5a0 fs/ntfs3/record.c:148

but task is already holding lock:
ffff888076f06840 (&ni->ni_lock/4){+.+.}-{3:3}, at: ni_lock fs/ntfs3/ntfs_fs.h:1124 [inline]
ffff888076f06840 (&ni->ni_lock/4){+.+.}-{3:3}, at: ntfs_lookup+0xf9/0x1f0 fs/ntfs3/namei.c:84

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
