Ok, well then that indeed seems to be a false positive from smatch. The pattern is this: get(fence); make_fence_point_to_something_different(&fence); put(fence); The make_fence_point_to_something_different() function consumes the original fence reference and returns a new one. So the get/put dance is completely correct. (Well it indeed doesn't make much sense, normally you would do something with the returned reference before calling put. But that here is just to test the make_fence_point_to_something_different() function). Regards, Christian. > > regards, > dan carpenter >
