From 4e1061f4a2bba1669c7297455c73ddafbebf2b12 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Tue, 21 Nov 2017 13:23:53 +0100 Subject: net/smc: use sk_rcvbuf as start for rmb creation Commit 3e034725c0d8 ("net/smc: common functions for RMBs and send buffers") merged handling of SMC receive and send buffers. It introduced sk_buf_size as merged start value for size determination. But since sk_buf_size is not used at all, sk_sndbuf is erroneously used as start for rmb creation. This patch makes sure, sk_buf_size is really used as intended, and sk_rcvbuf is used as start value for rmb creation.
