nm vmlinux | grep __fentry__ nm vmlinux | grep mcount 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
