[PATCH v4 7/8] kbuild: build sample modules along with the rest of the kernel

From: Nicolas Pitre
Date: Sun Feb 28 2016 - 22:48:49 EST


Make sample modules in parallel with the rest of the kernel rather
than having them built from the vmlinux target. This makes the build
slightly faster, and those modules are properly considered when
adjust_autoksyms.sh is executed.
