[PATCH v4] selftests: add headers_install to lib.mk
From: Anders Roxell
Date: Thu Jun 07 2018 - 07:09:29 EST
If the kernel headers aren't installed we can't build all the tests.
Add a new make target rule 'khdr' in the file lib.mk to generate the
kernel headers and that gets include for every test-dir Makefile that
includes lib.mk If the testdir in turn have its own sub-dirs the
top_srcdir needs to be set to the linux-rootdir to be able to generate
the kernel headers.
