Subject: Re: set_cpus_allowed_ptr

I tried the following semantic patch:

@@
expression E1,E2;
@@

- set_cpus_allowed(E1, cpumask_of_cpu(E2))
+ set_cpus_allowed_ptr(E1, cpumask_of(E2))

@@
expression E;
identifier I;
@@

- set_cpus_allowed(E, I)
+ set_cpus_allowed_ptr(E, &I)

@@
@@

+BAD(
 set_cpus_allowed(...)
+ )

I didn't get any occurrences of BAD in the output, so there seem to be 
only calls to cpumask_of_cpu and identifiers.  Looking at the result of 
grepping for set_cpus_allowed suggested the same.  Am I missing anything?
