syz.5.219/8183 is trying to acquire lock:

ffff0000fcec3148 (mapping.invalidate_lock#7){++++}-{3:3}, at: ntfs_fallocate+0x39c/0xfd0 fs/ntfs3/file.c:594

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:
  &ni->ni_lock/5 --> &vma->vm_lock->lock --> mapping.invalidate_lock#7

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(mapping.invalidate_lock#7);
                               lock(&vma->vm_lock->lock);
                               lock(mapping.invalidate_lock#7);
  lock(&ni->ni_lock/5);
