What were you trying to do that didn't work?
I'm testing a simple systemtap script but always get the following warning on x86_64:
[root@dell-r640-037 ~]# stap -gv nfsv3.stp Pass 1: parsed user script and 486 library scripts using 138284virt/106384res/13712shr/91952data kb, in 190usr/30sys/245real ms.

The script is like:
[root@dell-r640-037 ~]# cat nfsv3.stp
#!/usr/bin/stap -g
probe module("nfsv3").function("nfs3_proc_readdir") {
$nr_arg->plus = 1;
}
[root@dell-r640-037 ~]#
The systemtap version is:
[root@dell-r640-037 ~]# rpm -q systemtap systemtap-5.2-1.el10.x86_64 [root@dell-r640-037 ~]# stap --version Systemtap translator/driver (version 5.2/0.192/0.191, rpm 5.2-1.el10) Copyright (C) 2005-2024 Red Hat, Inc. and others This is free software; see the source for copying conditions. tested kernel versions: 3.10 ... 6.12-rc enabled features: AVAHI BOOST_STRING_REF DYNINST BPF JAVA PYTHON3 LIBRPM LIBSQLITE3 LIBVIRT LIBXML2 NLS NSS READLINE MONITOR_LIBS JSON_C LIBDEBUGINFOD [root@dell-r640-037 ~]#
Please help check if I'm wrongly using the stap tool and whether the warning affect the script's expected function. Thanks!
