perf test record+probe_libc_inet_pton: Fix call chain match on x86_64
The test case probe libc's inet_pton & backtrace it with ping fails with
Fedora 38 on x86_64.
Function getaddrinfo() does not show up in the call chain anymore:
# ./perf script
ping 1803 [000] 728.567146: probe_libc:inet_pton: (7f5275afc840)
133840 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6)
27b4a __libc_start_call_main+0x7a (/usr/lib64/libc.so.6)
27c0b __libc_start_main@@GLIBC_2.34+0x8b (/usr/lib64/libc.so.6)
ping 1803 [000] 728.567184: probe_libc:inet_pton: (7f5275afc840)
133840 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6)
493e main+0xcde (/usr/bin/ping)
27b4a __libc_start_call_main+0x7a (/usr/lib64/libc.so.6)
#
which causes the test case to fail. Remove function getaddrinfo()
from list of expected functions.
Output before:
# ./perf test 'libc'
91: probe libc's inet_pton & backtrace it with ping : FAILED!
#
Output after:
# ./perf test 'libc'
91: probe libc's inet_pton & backtrace it with ping : Ok
