From 9162e0ed9e238c1f1d738cb36ee59d96b097f8e1 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 8 Dec 2017 21:04:05 +0800 Subject: [PATCH 1/1] sctp: implement enqueue_event for sctp_stream_interleave enqueue_event is added as a member of sctp_stream_interleave, used to enqueue either data, idata or notification events into user socket rx queue. It replaces sctp_ulpq_tail_event used in the other places with enqueue_event. Signed-off-by: Xin Long Acked-by: Marcelo Ricardo Leitner Acked-by: Neil Horman Signed-off-by: David S.
