+What:   RCU API moves to EXPORT_SYMBOL_GPL
+When:   April 2006
+Files:  include/linux/rcupdate.h, kernel/rcupdate.c
+Why:    Outside of Linux, the only implementations of anything even
+        vaguely resembling RCU that I am aware of are in DYNIX/ptx,
+        VM/XA, Tornado, and K42.  I do not expect anyone to port binary
+        drivers or kernel modules from any of these, since the first two
+        are owned by IBM and the last two are open-source research OSes.
+        So these will move to GPL after a grace period to allow
+        people, who might be using implementations that I am not aware
+        of, to adjust to this upcoming change.
