From b87ba0a33a634c9a8e3609702122a04034a0688d Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 20 Mar 2006 13:17:13 -0800 Subject: [PATCH] add EXPORT_SYMBOL_GPL_FUTURE() to USB subsystem The USB core symbols will be converted to GPL-only in a few years. Mark this as such and update the documentation explaining why, and provide a pointer for developers to receive help if they need it.
