From 89cceaa939171fafa153d4bf637b39e396bbd785 Mon Sep 17 00:00:00 2001 From: Hechao Li Date: Mon, 10 Jun 2019 17:43:07 -0700 Subject: [PATCH] selftests/bpf : clean up feature/ when make clean An error "implicit declaration of function 'reallocarray'" can be thrown with the following steps: $ cd tools/testing/selftests/bpf $ make clean && make CC= $ make clean && make CC= The cause is that the feature folder generated by GCC 4.8.5 is not removed, leaving feature-reallocarray being 1, which causes reallocarray not defined when re-compliing with GCC 7.x. This diff adds feature folder to EXTRA_CLEAN to avoid this problem. v2: Rephrase the commit message.
