[PATCH v3 10/22] netconsole: Rename netconsole_target ->netpoll_target
From: Mike Waychison
Date: Tue Dec 14 2010 - 16:34:11 EST
Rename targets from "struct netconsole_target" to "struct
netpoll_target" as they will soon no longer be netconsole specific.
While here, also rename the configfs related types.
