In setup_namespace(), f_mountinfo is opened with fopen() at line 115 but is never closed. Multiple ksft_exit_fail_msg() calls exit the program without closing this file descriptor, and the cleanup_namespace() function registered with atexit() also doesn't close it. Add fclose(f_mountinfo) in cleanup_namespace() to ensure the file descriptor is properly closed on both normal and error exit paths, since cleanup_namespace() is already registered as an atexit handler.
