>Description:

A patch to create dynamic sysctl nodes at runtime

>How-To-Repeat:

N/A

>Fix:

The following code (and corresponding code for other data types supported
by sysctl) needs to go into /usr/src/sys/kern/kern_sysctl.c

void
sysctl_register_long(struct sysctl_oid_list *parent, int number, char *name,
		    int access, long *ptr, struct sysctl_oid *oidp)
{
	oidp->oid_parent = parent;
	SLIST_NEXT(oidp, oid_link) = NULL;
	oidp->oid_number = number;
	oidp->oid_name = name;
	oidp->oid_handler = sysctl_handle_long;
	oidp->oid_kind = CTLTYPE_INT | access;
	oidp->oid_arg1 = (void *) ptr;
	oidp->oid_arg2 = 0;
	oidp->oid_fmt = "L";

	/* Register this oid */
	sysctl_register_oid(oidp);
}
