/*
 * Register a set of sysctl names by calling register_sysctl_table
 * with an initialised array of ctl_table's.  An entry with zero
 * ctl_name and NULL procname terminates the table.  table->de will be
 * set up by the registration and need not be initialised in advance.
 *
 * sysctl names can be mirrored automatically under /proc/sys.  The
 * procname supplied controls /proc naming.
 *
 * The table's mode will be honoured both for sys_sysctl(2) and
 * proc-fs access.
 *
 * 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 entries with a zero ctl_name will not be available through
 * the binary sysctl interface.
 *
 * 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.
