16 /* * CTL_DEBUG variables. * * These are declared as separate variables so that they can be * individually initialized at the location of their associated * variable. The loader prevents multiple use by issuing errors * if a variable is initialized in more than one place. They are * aggregated into an array in debug_sysctl(), so that it can * conveniently locate them when queried. If more debugging * variables are added, they must also be declared here and also * entered into the array. * * Note that the debug subtree is largely obsolescent in terms of * functionality now that we have dynamic sysctl, but the * infrastructure is retained for backwards compatibility. */
