users have complained indicating there is no more need for these
boards. This should really be considered a last call.
Who: Ralf Baechle <ralf@linux-mips.org>
+
+---------------------------
+
+What: USB driver API moves to EXPORT_SYMBOL_GPL
+When: Febuary 2008
+Files: include/linux/usb.h, drivers/usb/core/driver.c
+Why: The USB subsystem has changed a lot over time, and it has been
+ possible to create userspace USB drivers using usbfs/libusb/gadgetfs
+ that operate as fast as the USB bus allows. Because of this, the USB
+ subsystem will not be allowing closed source kernel drivers to
+ register with it, after this grace period is over. If anyone needs
+ any help in converting their closed source drivers over to use the
+ userspace filesystems, please contact the
+ linux-usb-devel@lists.sourceforge.net mailing list, and the developers
+ there will be glad to help you out.
+Who: Greg Kroah-Hartman <gregkh@suse.de>
