From 3583df1a3d7328b42cf116db3fb56b0368fab12b Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 30 Jun 2017 11:52:19 +0800 Subject: [PATCH] sctp: remove the typedef sctp_datahdr_t This patch is to remove the typedef sctp_datahdr_t, and replace with struct sctp_datahdr in the places where it's using this typedef. It is also to use izeof(variable) instead of sizeof(type). Signed-off-by: Xin Long Signed-off-by: David S.
