Message-ID: <202308241323.ABBE0B09B@keescook> (raw)
In-Reply-To: <202308232200.1c932a90-oliver.sang@intel.com>
I was able to reproduce this failure. Yonghong, any ideas what's going
on here? I'm still trying to figure out what part of the
kallsyms_selftest actually failed (there are about 4 places that all
lead to this error message).
