From: Michal Suchanek <msuchanek@xxxxxxx> A recent bug report showed that modinfo doesn't give the signature information for certain modules, and it turned out to happen only on the modules that are built-in on the running kernel; then modinfo skips the signature check, as if the target module file never exists. The behavior is, however, inconsistent when modinfo is performed for external modules (no matter which kernel version is) and the module file path is explicitly given by a command-line argument, which guarantees the presence of the module file itself.
