From: Björn Töpel Date: Tue, 1 Oct 2019 11:33:06 +0000 (+0200) Subject: perf tools: Make usage of test_attr__* optional for perf-sys.h X-Git-Tag: v5.10.7~3816^2~29^2~54 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=06f84d1989b7e58d56fa2e448664585749d41221;p=platform%2Fkernel%2Flinux-rpi.git perf tools: Make usage of test_attr__* optional for perf-sys.h For users of perf-sys.h outside perf, e.g. samples/bpf/bpf_load.c, it's convenient not to depend on test_attr__*. After commit 91854f9a077e ("perf tools: Move everything related to sys_perf_event_open() to perf-sys.h"), all users of perf-sys.h will depend on test_attr__enabled and test_attr__open. This commit enables a user to define HAVE_ATTR_TEST to zero in order to omit the test dependency.
