From b984f370ed5182d180f92dbf14bdf847ff6ccc04 Mon Sep 17 00:00:00 2001 From: Wen Gu Date: Thu, 14 Jul 2022 17:44:03 +0800 Subject: [PATCH] net/smc: Use sysctl-specified types of buffers in new link group This patch introduces a new SMC-R specific element buf_type in struct smc_link_group, for recording the value of sysctl smcr_buf_type when link group is created. New created link group will create and reuse buffers of the type specified by buf_type. Signed-off-by: Wen Gu Signed-off-by: David S.
