1. No need to check if a list is empty before list_for_each_ looping as
this is already checked by loop stopping conditional.
The side effect is reduced indentation depth
from:
if (!list_empty)
list_for_each()
to:
list_for_each()
2. drop cb_ prefix from cl_pos, cl_next variables used in list_for_each
loops. The code is more compact and readable
