* Each subsystem defined by sysctl defines a list of variables
- * for that subsystem. Each name is either a node with further
+ * for that subsystem. Each name is either a node with further
* levels defined below it, or it is a leaf of some particular
* type given below. Each sysctl level defines a set of name/type
* pairs to be used by sysctl(1) in manipulating the subsystem.
+ *
+ * When declaring new sysctl names, use the CTLFLAG_LOCKED flag in the
+ * type to indicate that all necessary locking will be handled
+ * within the sysctl.
+ *
+ * Any sysctl defined without CTLFLAG_LOCKED is considered legacy
+ * and will be protected by a global mutex.
+ *
+ * Note: This is not optimal, so it is best to handle locking
+ * yourself, if you are able to do so. A simple design
+ * pattern for use to avoid in a single function known
+ * to potentially be in the paging path ot doing a DMA
+ * to physical memory in a user space process is:
+ *
+ * lock
+ * perform operation vs. local buffer
+ * unlock
+ * SYSCTL_OUT(rey, local buffer, length)
+ *
+ * ...this assumes you are not using a deep call graph
+ * or are unable to pass a local buffer address as a
+ * parameter into your deep call graph.
+ *
+ * Note that very large user buffers can fail the wire
+ * if to do so would require more physical pages than
+ * are available (the caller will get an ENOMEM error,
+ * see sysctl_mem_hold() for details).

+ * sysctl_unregister_oid() using the fact that the fields up
+ * to oid_fmt are unchanged, and that the field immediately
+ * following is on an alignment boundary following a pointer
+ * type and is also a pointer. This lets us get the previous
+ * size of the structure, and the copy-cut-off point, using
+ * the offsetof() language primitive, and these values are
+ * used in conjunction with the fact that earlier and future
+ * statically compiled sysctl_oid structures are declared via
+ * macros. This lets us overload the macros so that the addition
+ * of the CTLFLAG_OID2 in newly compiled code containing sysctl
+ * node declarations, subsequently allowing us to to avoid
+ * changing the KPI used for non-static (un)registration in
+ * KEXTs.
+ *
+ * This depends on the fact that people declare SYSCTLs,
+ * rather than declaring sysctl_oid structures. All new code
+ * should avoid declaring struct sysctl_oid's directly without
+ * the macros; the current risk for this is limited to losing
+ * your description field and ending up with a malloc'ed copy,
+ * as if it were a legacy binary static declaration via SYSCTL;
+ * in the future, we may deprecate access to a named structure
+ * type in third party code. Use the macros, or our code will
+ * end up with compile errors when that happens.
+ *
+ * Please try to include a long description of the field in any
+ * new sysctl declarations (all the macros support this). This
+ * field may be the only human readable documentation your users
+ * get for your sysctl.
