mptcp: fix syncookie build error on UP
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. Fixes: 9466a1ccebbe54 ("mptcp: enable JOIN requests even if cookies are in use") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
