From edf903f83ebca988e04a39f515ab6eacb92055df Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 11 Aug 2017 10:23:46 +0800 Subject: sctp: remove the typedef sctp_sender_hb_info_t This patch is to remove the typedef sctp_sender_hb_info_t, and replace with struct sctp_sender_hb_info in the places where it's using this typedef. It is also to use sizeof(variable) instead of sizeof(type). Signed-off-by: Xin Long Signed-off-by: David S.
