A bit of clarification happened for its implementation details.

I have taken also another look at the following SmPL code.


> identifier fn =~
> "^(__pte_alloc|pte_alloc_one|pte_alloc|__pte_alloc_kernel|pte_alloc_one_kernel)$";

I suggest to adjust the regular expression for this constraint
and in subsequent SmPL rules.

"^(?:pte_alloc(?:_one(?:_kernel)?)?|__pte_alloc(?:_kernel)?)$";

I propose to take an other SmPL disjunction into account here.

 T3 fn(T1 E1,
(
-      T2 E2
|      T2 E2,
-      T4 E4
)      );

How do you think about to omit the metavariable “position p” here?
