This resolves the following compilation error: ld: net/core/sock.o: in function `sk_defer_free_flush': ./include/net/tcp.h:1378: undefined reference to `__sk_defer_free_flush' Fixes: 79074a72d335 ("net: Flush deferred skb free on socket destroy") Reported-by: kernel test robot <lkp@...el.com> Reviewed-by: Tariq Toukan <tariqt@...dia.com> Signed-off-by: Gal Pressman <gal@...dia.com> Reviewed-by: Eric Dumazet <edumazet@...gle.com> Link: https://lore.kernel.org/r/20220120123440.9088-1-gal@nvidia.com Signed-off-by: Jakub Kicinski <kuba@...nel.org>
