From: Stanislav Lisovskiy <stanislav.lisovskiy@xxxxxxxxx>
Ultrajoiner case requires special treatment where both reverse and
staight order iteration doesn't work(for instance disabling case requires
order to be: primary master, slaves, secondary master).
Lets unify our approach by using not only pipe masks for iterating required
pipes based on joiner type used, but also using different "priority" arrays
for each of those.
v2: Fix checkpatch warnings. (Ankit)
