syz-executor.0/30933 is trying to acquire lock:
ffff8880568e1e80 (&ni->ni_lock#3){+.+.}-{3:3}, at: ntfs_set_state+0x212/0x730 fs/ntfs3/fsntfs.c:946

but task is already holding lock:

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  &ni->ni_lock#3 --> &wnd->rw_lock/1 --> &ni->file.run_lock#2

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&ni->file.run_lock#2);
                               lock(&wnd->rw_lock/1);
                               lock(&ni->file.run_lock#2);
  lock(&ni->ni_lock#3);
