+ If enabled, this option will also move any device structures
+ that belong to a class, back into the /sys/class heirachy, in

- Enable the deprecated sysctl system call. sys_sysctl uses

- everyone uses.
+ sys_sysctl uses binary paths that have been found challenging
+ to properly maintain and use. The interface in /proc/sys
+ using paths with ascii names is now the primary path to this
+ information.
- Nothing has been using the binary sysctl interface for some time
- time now so nothing should break if you disable sysctl syscall
- support, and you kernel will get marginally smaller.
+ Almost nothing using the binary sysctl interface so if you are
+ trying to save some space it is probably safe to disable this,

- you should probably say N here.
