WARNING: possible recursive locking detected

--------------------------------------------
kworker/u4:32/16490 is trying to acquire lock:
ffff888082d44360 (&ni->ni_lock){+.+.}-{3:3}, at: ntfs_set_state+0x212/0x730 fs/ntfs3/fsntfs.c:946

but task is already holding lock:
ffff888077758100 (&ni->ni_lock){+.+.}-{3:3}, at: ni_trylock fs/ntfs3/ntfs_fs.h:1144 [inline]
ffff888077758100 (&ni->ni_lock){+.+.}-{3:3}, at: ni_write_inode+0x163/0x1070 fs/ntfs3/frecord.c:3256

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
