--------------------------------------------
kworker/u16:15/21035 is trying to acquire lock:
ffff88802d8a9920 (&ni->ni_lock#3){+.+.}-{3:3}, at: ntfs_set_state+0x1d2/0x6e0 fs/ntfs3/fsntfs.c:946

but task is already holding lock:
ffff888066db1860 (&ni->ni_lock#3){+.+.}-{3:3}, at: ni_trylock fs/ntfs3/ntfs_fs.h:1144 [inline]

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

       CPU0
       ----
  lock(&ni->ni_lock#3);
  lock(&ni->ni_lock#3);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
