[PATCH] perf/tests: fix record+probe_libc_inet_pton test on aarch64

From: Jing Zhang
Date: Tue Oct 15 2024 - 03:53:56 EST


Since commit 1f85d016768f ("perf test record+probe_libc_inet_pton: Fix
call chain match on x86_64") remove function getaddrinfo() on expected
file, the test failed on aarch64. On aarch64, function getaddrinfo()
show up in the call chain.

$perf script -i /tmp/perf.data.1PV
ping 2588319 [125] 500119.122843: probe_libc:inet_pton: (ffff9a4f7410)
ffff9a4f7410 __GI___inet_pton+0x0 (/usr/lib64/libc-2.32.so)
ffff9a4c5f7c getaddrinfo+0xec (/usr/lib64/libc-2.32.so)
aaaad6d32b38 [unknown] (/usr/bin/ping)

So just remove getaddrinfo() on x86_64.
