From: Arnaldo Carvalho de Melo Date: Mon, 6 Aug 2018 12:46:33 +0000 (-0300) Subject: perf bpf: Make bpf__for_each_stdout_map() generic X-Git-Tag: v4.19~274^2~1^2~44 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5941d856a90435b32a3296c0b7df8f0075430b81;p=platform%2Fkernel%2Flinux-rpi.git perf bpf: Make bpf__for_each_stdout_map() generic By passing a 'name' arg, that will eventually be used to setup more "bpf-output" events, e.g. to create a event where to create raw_syscalls like events that in addition to the syscall arguments will also copy the pointer contents being passed from/to userspace.
