From: Arnaldo Carvalho de Melo Date: Wed, 12 Dec 2018 18:31:28 +0000 (-0300) Subject: perf bpf: Move perf_event_output() from stdio.h to bpf.h X-Git-Tag: v5.4-rc1~1977^2^2~40 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=61d007138a44dc69265cf948eadd1759edbd3875;p=platform%2Fkernel%2Flinux-rpi.git perf bpf: Move perf_event_output() from stdio.h to bpf.h So that we don't always carry that __bpf_output__ map, leaving that to the scripts wanting to use that facility. 'perf trace' will be changed to look if that map is present and only setup the bpf-output events if so.
