My pattern recognition needed a while to take another software design approach into account.

Corresponding SmPL script example:
@display disable braces0@
iterator name SYSCALL_DEFINE0;
@@
*SYSCALL_DEFINE0(...)
 {
 ...
 }


Questionable test result (according to the software combination “Coccinelle 1.3.1”):

How will the clarification be continued for more desirable software behaviour?
