What do these report ? I bet you that in your vmlinux the first one
would return something like :

ffffffff822f1810 T __fentry__
ffffffff827fdc20 r __kcrctab___fentry__
ffffffff82809461 r __kstrtab___fentry__
ffffffff827e6c20 R __ksymtab___fentry__
and nothing for the second. Whereas doing nm on the module in question
would give nothing for __fentry__ and something like: U mcount
