Subject: [PATCH] selftests/bpf: split -extras target to -static and -gen
Date: Fri, 22 May 2020 11:19:01 +0300
Message-ID: <20200522081901.238516-1-yauheni.kaliuta@redhat.com> (raw)
In-Reply-To: <xuny367so4k3.fsf@redhat.com>

There is difference in depoying static and generated extra resource
files between in/out of tree build and flavors:

- in case of unflavored out-of-tree build static files are not
available and must be copied as well as both static and generated
files for flavored build.

So split the rules and variables. The name TRUNNER_EXTRA_GEN_FILES
is chosen in analogy to TEST_GEN_* variants.
