Subject: [PATCH 07/16] netconsole: factor out alloc_netconsole_target()
Date: Thu, 16 Apr 2015 19:03:44 -0400 [thread overview]
Message-ID: <1429225433-11946-8-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1429225433-11946-1-git-send-email-tj@kernel.org>
alloc_param_target() and make_netconsole_target() were duplicating the
same allocation and init logic. Factor it out to
alloc_netconsole_target().
This is pure reorganization.
