+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.

+What: find_trylock_page
+When: January 2007
+Why: The interface no longer has any callers left in the kernel. It
+ is an odd interface (compared with other find_*_page functions), in
+ that it does not take a refcount to the page, only the page lock.
+ It should be replaced with find_get_page or find_lock_page if possible.
+ This feature removal can be reevaluated if users of the interface
+ cannot cleanly use something else.
