From: Rao Shoaib <rao.shoaib@xxxxxxxxxx>
Example:
CHECK: Macro argument reuse 'ptr' - possible side-effects?
+#define kfree_rcu(ptr, rcu_name) \
+ do { \
+ unsigned long __off = offsetof(typeof(*(ptr)), rcu_name); \
+ struct rcu_head *__rptr = (void *)ptr + __off; \
+ __kfree_rcu(__rptr, __off); \
+ } while (0)
Fix supplied by Joe Perches.
