+What:	sys_sysctl
+When:	September 2010
+Option: CONFIG_SYSCTL_SYSCALL
+Why:	The same information is available in a more convenient from
+	/proc/sys, and none of the sysctl variables appear to be
+	important performance wise.
+
+	Binary sysctls are a long standing source of subtle kernel
+	bugs and security issues.
+
+	When I looked several months ago all I could find after
+	searching several distributions were 5 user space programs and
+	glibc (which falls back to /proc/sys) using this syscall.
+
+	The man page for sysctl(2) documents it as unusable for user
+	space programs.
+
+	sysctl(2) is not generally ABI compatible to a 32bit user
+	space application on a 64bit and a 32bit kernel.
+
+	For the last several months the policy has been no new binary
+	sysctls and no one has put forward an argument to use them.
+
+	Binary sysctls issues seem to keep happening appearing so
+	properly deprecating them (with a warning to user space) and a
+	2 year grace warning period will mean eventually we can kill
+	them and end the pain.
+
+	In the mean time individual binary sysctls can be dealt with
+	in a piecewise fashion.
