This could just be links = links->next like you have later.
I just used "next" because I had it available here but not
below. I do like consistency though so I'll make your
suggested change.
After looking at it again, I don't think you're right.
The reason is that __rbd_remove_snap_dev() actually unlinks
the "snap" from the list that contains it, and "links" at
this point is referring to &snap->node, which is modified
by the list deletion.
The assignment I had originally, which uses a saved copy
of links->next, is the correct one. So I'll be committing
with my original version of this section of code.
