This series fixes a bug in the map_lookup_and_delete_elem() function which
should check for the FMODE_CAN_READ bit, because it returns data to user space.
The rest of commits fix some typos and comment in selftests and extend the
test_map_wronly test to cover the new check for the BPF_MAP_TYPE_STACK and
BPF_MAP_TYPE_QUEUE map types.
