coccinelle: api: check for macro context

2026-08-23T20:12:10+00:00

A cast on a call to an allocation function that is the body of a macro can be useful, as it ensures tha the macro is used for allocating objects of the right type. Add two new rules to ignore the macro case. Suggested-by: Steven Rostedt Signed-off-by: Julia Lawall
