From 9dc4bcb1a63acbbe32b4e80b690a843dd37315e7 Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Fri, 7 Mar 2025 18:32:58 -0700 Subject: [PATCH] build(7): Document KERNBUILDDIR KERNBUILDDIR is used by kmod.mk to find the opt_*.h when matching a kernel to the module. Usually one doesn't need this nob (since most modules are option invariant or default to the default options everyone uses), but there are times this generalization doesn't hold.
