From c525ec74b44f471261b0e67eaa254e05fdef3d05 Mon Sep 17 00:00:00 2001 From: Zhenlei Huang Date: Thu, 12 Oct 2023 18:14:48 +0800 Subject: [PATCH] boottrace: Add corresponding sysctl knob for loader tunable The loader tunable 'kern.boottrace.table_size' does not have corresponding sysctl MIB entry. Add it so that it can be retrieved, and `sysctl -T` will also report it correctly.
