Subject: [PATCH] kbuild: install-extmod-build: install kernel/kallsyms_internal.h
Date: Mon, 5 Oct 2026 20:01:23 +0000 [thread overview]
Message-ID: <20261005200123.146822-1-denis.benato@linux.dev> (raw)
The tree staged by install-extmod-build contains no kernel/ files, but
since commit 4fafd1165b33 ("kallsyms: increase marker density to 16:1
to accelerate lookups") scripts/kallsyms.c includes
../kernel/kallsyms_internal.h.
install-extmod-build rebuilds the host programs inside the staged tree
whenever CC differs from HOSTCC (cross builds, or a ccache-wrapped CC).
scripts/kallsyms is hostprogs-always-y, so that rebuild fails with:
scripts/kallsyms.c:39:10: fatal error: '../kernel/kallsyms_internal.h' file not found
39 | #include "../kernel/kallsyms_internal.h"
| ^~~~~~~
Stage the header so the linux-headers-* and kernel-devel style packages
can rebuild scripts/kallsyms.
Fixes: 4fafd1165b33 ("kallsyms: increase marker density to 16:1 to accelerate lookups")
