Subject: [PATCH v16 33/45] sg: move procfs objects to avoid forward decls
Date: Fri, 19 Feb 2021 21:00:44 -0500 [thread overview]
Message-ID: <20210220020056.77483-34-dgilbert@interlog.com> (raw)
In-Reply-To: <20210220020056.77483-1-dgilbert@interlog.com>
Move the procfs related file_operations and seq_operations
definitions toward the end of the source file to minimize the
need for forward declarations of the functions they name.
