1388 * __register_sysctl_init() - register sysctl table to path
1389 * @path: path name for sysctl base
1390 * @table: This is the sysctl table that needs to be registered to the path
1391 * @table_name: The name of sysctl table, only used for log printing when
1392 * registration fails
1393 *
1394 * The sysctl interface is used by userspace to query or modify at runtime
1395 * a predefined value set on a variable. These variables however have default
1396 * values pre-set. Code which depends on these variables will always work even
1397 * if register_sysctl() fails. If register_sysctl() fails you'd just loose the
1398 * ability to query or modify the sysctls dynamically at run time. Chances of
1399 * register_sysctl() failing on init are extremely low, and so for both reasons
1400 * this function does not return any error as it is used by initialization code.
1401 *
1402 * Context: Can only be called after sysctl base path has been registered
1403 * It is recommended to call this interface in core_initcall() and
1404 * later initcall(), not in early_initcall() and earlier stages.
