Message-Id: <f21861d502b04cf3752dce4cde8cd3f5f1806571.1461511282.git.lucien.xin@gmail.com> Date: Sun, 24 Apr 2016 23:21:22 +0800 From: Xin Long <lucien.xin@...il.com> To: network dev <netdev@...r.kernel.org>, linux-sctp@...r.kernel.org Cc: Marcelo Ricardo Leitner <marcelo.leitner@...il.com>, Vlad Yasevich <vyasevich@...il.com>, daniel@...earbox.net, davem@...emloft.net, eric.dumazet@...il.com Subject: [PATCH net-next] sctp: sctp_diag should fill RMEM_ALLOC with asoc->rmem_alloc when rcvbuf_policy is set For sctp assoc, when rcvbuf_policy is set, it will has it's own rmem_alloc, when we dump asoc info in sctp_diag, we should use that value on RMEM_ALLOC as well, just like WMEM_ALLOC.
