From 5509bad74e44eed3b9d54fbd74d3752b88428147 Mon Sep 17 00:00:00 2001 From: Rick Macklem Date: Tue, 16 Nov 2021 16:02:53 -0800 Subject: [PATCH] nfsd: Add a new rc variable nfs_server_maxio Since vfs.nfsd.srvmaxio can only be set when nfsd.ko is loaded, but nfsd is not running, setting it in /etc/sysctl.conf is not feasible when "options NFSD" was not specified for the kernel. This patch adds a new rc variable nfs_server_maxio, which sets vfs.nfsd.srvmaxio at the correct time. rc.conf.5 will be patched separately.
