--------------------------------------------
kworker/u4:12/3904 is trying to acquire lock:
ffff8880702d0100 (&ni->ni_lock){+.+.}-{3:3}, at: ntfs_set_state+0x1fa/0x660 fs/ntfs3/fsntfs.c:920

but task is already holding lock:
ffff8880702d6fa0 (&ni->ni_lock){+.+.}-{3:3}, at: ni_trylock fs/ntfs3/ntfs_fs.h:1116 [inline]
ffff8880702d6fa0 (&ni->ni_lock){+.+.}-{3:3}, at: ni_write_inode+0x16b/0x1070 fs/ntfs3/frecord.c:3318

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
