From: Al Viro <[email protected]> the only in-tree instance checks d_unhashed() anyway, out-of-tree code can preserve the current behaviour by adding such check if they want it and we get an ability to use it in cases where we *want* to be notified of killing being inevitable before ->d_lock is dropped, whether it's unhashed or not. In particular, autofs would benefit from that.
