Re: [PATCH] selftests/net: skip psock_tpacket test if KALLSYMS was not enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This issue was spotted on Ubuntu linux-kvm kernel, on which the
CONFIG_KALLSYMS was disabled intentionally.
I think this extra check could be helpful when running the net test directly.
$ make -C tools/testing/selftests TARGETS=net run_tests

Also, there is an identical check implemented in the ftrace
kprobe_args_symbol test.

I can send V2 along with CONFIG_KALLSYMS appended to the "config" file
if you agree with this.

Thanks
