-What: sys_sysctl
-When: January 2007
-Why: The same information is available through /proc/sys and that is the
- interface user space prefers to use. And there do not appear to be
- any existing user in user space of sys_sysctl. The additional
- maintenance overhead of keeping a set of binary names gets
- in the way of doing a good job of maintaining this interface.

+ sys_sysctl uses binary paths that have been found challenging

- Nothing has been using the binary sysctl interface for some

- support, and your kernel will get marginally smaller.
+ Almost nothing using the binary sysctl interface so if you are
