From 034bfadc8f511397d55ad5a6851d796342d3c1f5 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Thu, 21 Jul 2022 10:35:46 -0400 Subject: [PATCH] Documentation: fix sctp_wmem in ip-sysctl.rst [ Upstream commit aa709da0e032cee7c202047ecd75f437bb0126ed ] Since commit 1033990ac5b2 ("sctp: implement memory accounting on tx path"), SCTP has supported memory accounting on tx path where 'sctp_wmem' is used by sk_wmem_schedule(). So we should fix the description for this option in ip-sysctl.rst accordingly. v1->v2: - Improve the description as Marcelo suggested.
