Subject[PATCH 35/44] perf bpf: Make bpf__for_each_stdout_map() generic
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

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.
