Subject: [PATCH net-next v3 1/4] netconsole: move init/cleanup functions lower
Date: Tue, 10 Oct 2023 02:37:48 -0700 [thread overview]
Message-ID: <20231010093751.3878229-2-leitao@debian.org> (raw)
In-Reply-To: <20231010093751.3878229-1-leitao@debian.org>
Move alloc_param_target() and its counterpart (free_param_target())
to the bottom of the file. These functions are called mostly at
initialization/cleanup of the module, and they should be just above the
callers, at the bottom of the file.
From a practical perspective, having alloc_param_target() at the bottom
of the file will avoid forward declaration later (in the following
patch).
Nothing changed other than the functions location.
