This patch fails on s390. I used 4.17.0rc5 + fedora 27 and I get this output:
[root@p23lp27 perf]# ./perf test 59
59: probe libc's inet_pton & backtrace it with ping : Ok
[root@p23lp27 linux]# cd ~/linux; patch -p1 < ../inet_pton1
(Stripping trailing CRs from patch; use --binary to disable.)
patching file tools/perf/tests/shell/record+probe_libc_inet_pton.sh
[root@p23lp27 linux]# cd -;
[root@p23lp27 perf]# ./perf test 59
59: probe libc's inet_pton & backtrace it with ping : FAILED!
[root@p23lp27 perf]#
Debugging revealed this line as cause of failure:
FAIL: expected backtrace entry 2 "gaih_inet.*\+0x[[:xdigit:]]+[[:space:]]\(/usr/lib64/libc-2.26.so|inlined\)$" got "fdcb1 gaih_inet.constprop.7 (/usr/lib64/libc-2.26.so)"
Here is the output of the trace file
[root@p23lp27 perf]# perf script
ping 87291 [001] 96936.231618: probe_libc:inet_pton: (3ff96342378)

Hope this helps

Can you please apply these two patches as well and then re-test?

Actually I'll fold this patch into the patch that made this test break,
so that we keep the tree bisectable wrt that specific 'perf test' entry.

Looks like perf failed to resolve the symbol's name for the last entry
in the callchain. I did not consider this case. So, if this happens, we
would be better off using the original regex for the last line:
expected[3]=".*\(.*/bin/ping.*\)$"

it...

[root@seventh perf]#
[root@seventh perf]# dnf debuginfo-install iputils

5585e10adf40 main+0x880 (/usr/bin/ping)

So we need to check if debuginfo is available, and if so, expect it to
resolve that entry to main, if not, expect it to _not_ resolve and have
[unknown] instead...

But tis is not related to your recent patches, so I'm folding this last
one with the one adding the offsets and go on from there...
