samples/bpf: Remove perf_event_open() declaration
This declaration was made in samples/bpf/libbpf.c for convenience, but there's already one in tools/perf/perf-sys.h. Reuse that one. Committer notes: Testing it: $ make -j4 O=../build/v4.9.0-rc8+ samples/bpf/ make[1]: Entering directory '/home/build/v4.9.0-rc8+' CHK include/config/kernel.release GEN ./Makefile CHK include/generated/uapi/linux/version.h Using /home/acme/git/linux as source for kernel CHK include/generated/utsrelease.h CHK include/generated/timeconst.h CHK include/generated/bounds.h CHK include/generated/asm-offsets.h CALL /home/acme/git/linux/scripts/checksyscalls.sh HOSTCC samples/bpf/test_verifier.o HOSTCC samples/bpf/libbpf.o HOSTCC samples/bpf/../../tools/lib/bpf/bpf.o HOSTCC samples/bpf/test_maps.o HOSTCC samples/bpf/sock_example.o HOSTCC samples/bpf/bpf_load.o <SNIP> HOSTLD samples/bpf/trace_event HOSTLD samples/bpf/sampleip HOSTLD samples/bpf/tc_l2_redirect make[1]: Leaving directory '/home/build/v4.9.0-rc8+' $ Also tested the offwaketime resulting from the rebuild, seems to work as before.
