From d18decca69e36480247a73086336f4a44a08e36f Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 15 May 2023 15:37:50 +0200 Subject: [PATCH] selftests/bpf: Use only stdout in un/load_bpf_testmod functions We are about to use un/load_bpf_testmod functions in couple tests and it's better to print output to stdout, so it's aligned with tests ASSERT macros output, which use stdout as well.
