- *
- * sysctl names can be mirrored automatically under /proc/sys. The

- *
- * The table's mode will be honoured both for sys_sysctl(2) and

- * Leaf nodes in the sysctl tree will be represented by a single file
- * under /proc; non-leaf nodes will be represented by directories. A
- * null procname disables /proc mirroring at this node.
- *
- * sysctl(2) can automatically manage read and write requests through
- * the sysctl table. The data and maxlen fields of the ctl_table
- * struct enable minimal validation of the values being written to be
- * performed, and the mode field allows minimal authentication.
- *
- * More sophisticated management can be enabled by the provision of a
- * strategy routine with the table entry. This will be called before
- * any automatic read or write of the data is performed.
- *
- * The strategy routine may return:
- * <0: Error occurred (error is passed to user process)
- * 0: OK - proceed with automatic read or write.
- * >0: OK - read or write has been done by the strategy routine, so
- * return immediately.
- *
- * There must be a proc_handler routine for any terminal nodes
- * mirrored under /proc/sys (non-terminals are handled by a built-in
- * directory handler). Several default handlers are available to
- * cover common cases.
