I think we are better off without this kind of changes, unless they are part of a largish re-factor. Thanks, Paolo

in randomize function, there is a open function, but there is no close function in the randomize, which is easy to cause memory leaks. Signed-off-by: Liu Jing <liujing@cmss.chinamobile.com> --- tools/testing/selftests/net/tcp_mmap.c | 1 + 1 file changed, 1 insertion(+)
