This system call has been deprecated almost since it was introduced, and in a survey of the linux distributions I can no longer find any of them that enable CONFIG_SYSCTL_SYSCALL. The only indication that I can find that anyone might care is that a few of the defconfigs in the kernel enable CONFIG_SYSCTL_SYSCALL. However this appears in only 31 of 414 defconfigs in the kernel, so I suspect this symbols presence is simply because it is harmless to include rather than because it is necessary. As there appear to be no users of the sysctl system call, remove the code. As this removes one of the few uses of the internal kernel mount of proc I hope this allows for even more simplifications of the proc filesystem.
