kernel test robot says: net/mptcp/syncookies.c: In function 'mptcp_join_cookie_init': include/linux/kernel.h:47:38: warning: division by zero [-Wdiv-by-zero] #define ARRAY_SIZE(arr) (sizeof(arr) / sizeof((arr)[0]) + __must_be_array(arr)) I forgot that spinock_t size is 0 on UP, so ARRAY_SIZE cannot be used.
