syz-executor.1/30827 is trying to acquire lock:
ffff888094af0100 (&ni->ni_lock){+.+.}-{3:3}, at: ntfs_set_state+0x217/0x6f0 fs/ntfs3/fsntfs.c:920

but task is already holding lock:
ffff888094af7700 (&ni->ni_lock){+.+.}-{3:3}, at: ni_trylock fs/ntfs3/ntfs_fs.h:1124 [inline]
ffff888094af7700 (&ni->ni_lock){+.+.}-{3:3}, at: ni_write_inode+0x151/0x1240 fs/ntfs3/frecord.c:3240

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

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

 *** DEADLOCK ***

 May be due to missing lock nesting notation
