Subject: [PATCH v9 01/14] module: Move all into module/
Date:   Mon, 28 Feb 2022 23:43:09 +0000
Message-Id: <20220228234322.2073104-2-atomlin@redhat.com>
In-Reply-To: <20220228234322.2073104-1-atomlin@redhat.com>

No functional changes.

This patch moves all module related code into a separate directory,
modifies each file name and creates a new Makefile. Note: this effort
is in preparation to refactor core module code.
