From cee360ab4dd66fc1de33a5fa1cb418fa21c27ce3 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Wed, 31 May 2017 16:36:31 +0800 Subject: sctp: define the member stream as an object instead of pointer in asoc As Marcelo's suggestion, stream is a fixed size member of asoc and would not grow with more streams. To avoid an allocation for it, this patch is to define it as an object instead of pointer and update the places using it, also create sctp_stream_update() called in sctp_assoc_update() to migrate the stream info from one stream to another.
