Subject: [PATCH] libkmod: Provide info even for modules built into the running
kernel.

Subject: [PATCH v2] libkmod: Set builtin to no when module is created from path.
Date: Wed, 18 Aug 2021 14:24:39 -0700
Message-Id: <20210818212440.2224127-1-lucas.demarchi@intel.com>
From: Michal Suchanek <msuchanek@suse.de>
When a module is built-in examining the module file is skipped.
However, a module that is built into the runnig kernel may be separate
in another kernel. Always examine the module file if it exists.
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.
Fixes: e7e2cb61fa9f ("modinfo: Show information about built-in modules")
