 Why:	Replaced by ->compat_ioctl in file_operations and other method

 Who:	Andi Kleen <ak@muc.de>, Christoph Hellwig <hch@lst.de>

+---------------------------
+
+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.
