[PATCH net-next v4 1/4] netconsole: move init/cleanup functions lower

From: Breno Leitao
Date: Thu Oct 12 2023 - 07:14:34 EST


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.
