---------------------------
-What: USB driver API moves to EXPORT_SYMBOL_GPL
-When: February 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>
-
----------------------------
-
What: vm_ops.nopage
When: Soon, provided in-kernel callers have been converted
Why: This interface is replaced by vm_ops.fault, but it has been around
