perf bpf: Clone bpf stdout events in multiple bpf scripts
This patch allows cloning bpf-output event configuration among multiple
bpf scripts. If there exist a map named '__bpf_output__' and not
configured using 'map:__bpf_output__.event=', this patch clones the
configuration of another '__bpf_stdout__' map. For example, following
command:
# perf trace --ev bpf-output/no-inherit,name=evt/ \
--ev ./test_bpf_trace.c/map:__bpf_stdout__.event=evt/ \
--ev ./test_bpf_trace2.c usleep 100000
equals to:
# perf trace --ev bpf-output/no-inherit,name=evt/ \
--ev ./test_bpf_trace.c/map:__bpf_stdout__.event=evt/ \
--ev ./test_bpf_trace2.c/map:__bpf_stdout__.event=evt/ \
usleep 100000
