perf test: "probe libc's inet_pton" fails on s390 due to missing inline
perf test "probe libc's inet_pton & backtrace it with ping" fails on 4.17.0rc3 on s/390. It turned out that function __inet_pton is reported as inline: [root@s8360047 perf]# ./perf script -i /tmp/perf.data.111 ping 12457 [000] 1584.478959: probe_libc:inet_pton: (3ffb5a347e8) 1347e8 __inet_pton (inlined) f19d7 gaih_inet.constprop.5 (/usr/lib64/libc-2.24.so) f4c3f __GI_getaddrinfo (inlined) 410b main (/usr/bin/ping) Allow __inet_pton listed as inline.
